 <p>The <a href="https://wiki2.dovecot.org/Plugins/FTS/Solr">dovecot-solr Plugin</a> is used in conjunction with <a href="https://lucene.apache.org/solr/">Apache Solr</a> running in a separate container. This is quite straightforward to setup using the following instructions.</p>

+<p>Solr is a mature and fast indexing backend that runs on the JVM. The indexes are relatively compact compared to the size of your total email.</p>
 <p>However, Solr also requires a fair bit of RAM. While Solr is <a href="https://solr.apache.org/guide/7_0/query-settings-in-solrconfig.html">highly tuneable</a>, it may require a bit of testing to get it right.</p>

 <p>If your container host supports IPv6, then <code>docker-mailserver</code> will automatically accept IPv6 connections by way of the docker host's IPv6. However, incoming mail will fail SPF checks because they will appear to come from the IPv4 gateway that docker is using to proxy the IPv6 connection (<code>172.20.0.1</code> is the gateway).</p>
 <p>This can be solved by supporting IPv6 connections all the way to the <code>docker-mailserver</code> container.</p>

 <p>We can also make use of user-provided configuration files, e.g. <code>user-patches.sh</code>, <code>postfix-accounts.cf</code> and more, to adjust <code>docker-mailserver</code> to our likings. We encourage you to have a look at <a href="https://kustomize.io/">Kustomize</a> for creating <code>ConfigMap</code>s from multiple files, but for now, we will provide a simple, hand-written example. This example is absolutely minimal and only goes to show what can be done.</p>

 <h3 id="service"><a class="toclink" href="#service">Service</a></h3>
 <p>A <code>Service</code> is required for getting the traffic to the pod itself. The service is somewhat crucial. Its configuration determines whether the original IP from the sender will be kept. <a href="#exposing-your-mail-server-to-the-outside-world">More about this further down below</a>.</p>
 <p>The configuration you're seeing does keep the original IP, but you will not be able to scale this way. We have chosen to go this route in this case because we think most Kubernetes users will only want to have one instance.</p>

 <p>Last but not least, the <code>Deployment</code> becomes the most complex component. It instructs Kubernetes how to run the <code>docker-mailserver</code> container and how to apply your <code>ConfigMaps</code>, persisted storage, etc. Additionally, we can set options to enforce runtime security here.</p>

 <p>In this example, we use <a href="https://cert-manager.io/docs/"><code>cert-manager</code></a> to supply RSA certificates. You can also supply RSA certificates as fallback certificates, which <code>docker-mailserver</code> supports out of the box with <code>SSL_ALT_CERT_PATH</code> and <code>SSL_ALT_KEY_PATH</code>, and provide ECDSA as the proper certificates.</p>

 <h2 id="exposing-your-mail-server-to-the-outside-world"><a class="toclink" href="#exposing-your-mail-server-to-the-outside-world">Exposing your Mail-Server to the Outside World</a></h2>
 <p>The more difficult part with Kubernetes is to expose a deployed <code>docker-mailserver</code> to the outside world. Kubernetes provides multiple ways for doing that; each has downsides and complexity. The major problem with exposing <code>docker-mailserver</code> to outside world in Kubernetes is to <a href="https://kubernetes.io/docs/tutorials/services/source-ip">preserve the real client IP</a>. The real client IP is required by <code>docker-mailserver</code> for performing IP-based SPF checks and spam checks. If you do not require SPF checks for incoming mails, you may disable them in your <a href="../override-defaults/postfix/">Postfix configuration</a> by dropping the line that states: <code>check_policy_service unix:private/policyd-spf</code>.</p>
-<p>The easiest approach was covered above, using <code class="highlight"><span class="nt">externalTrafficPolicy</span><span class="p">:</span><span class="w"> </span><span class="l l-Scalar l-Scalar-Plain">Local</span><span class="w"></span></code>, which disables the service proxy, but makes the service local as well (which does not scale). This approach only works when you are given the correct (that is, a public and routable) IP address by a load balancer (like MetalLB). In this sense, the approach above is similar to the next example below. We want to provide you with a few alternatives too. <strong>But</strong> we also want to communicate the idea of another simple method: you could use a load-balancer without an external IP and DNAT the network traffic to the mail-server. After all, this does not interfere with SPF checks because it keeps the origin IP address. If no dedicated external IP address is available, you could try the latter approach, if one is available, use the former.</p>

 <h3 id="external-ips-service"><a class="toclink" href="#external-ips-service">External IPs Service</a></h3>
 <p>The simplest way is to expose <code>docker-mailserver</code> as a <a href="https://kubernetes.io/docs/concepts/services-networking/service">Service</a> with <a href="https://kubernetes.io/docs/concepts/services-networking/service/#external-ips">external IPs</a>. This is very similar to the approach taken above. Here, an external IP is given to the service directly by you. With the approach above, you tell your load-balancer to do this.</p>

The authentication mechanisms are the same as for the main dovecot service. ManageSieve runs on port <code>4190</code> and needs to be enabled using the <code>ENABLE_MANAGESIEVE=1</code> environment variable.</p>

   <h1>Auto-discovery</h1>
 
 <p>Email auto-discovery means a client email is able to automagically find out about what ports and security options to use, based on the mail-server URI. It can help simplify the tedious / confusing task of adding own's email account for non-tech savvy users.</p>
-<p>Email clients will search for auto-discoverable settings and prefill almost everything when a user enters its email address <img alt="❤" class="twemoji" src="https://twemoji.maxcdn.com/v/latest/svg/2764.svg" title=":heart:" /></p>

 </div>
 <h2 id="enabling-dkim-signature"><a class="toclink" href="#enabling-dkim-signature">Enabling DKIM Signature</a></h2>
 <p>To enable DKIM signature, <strong>you must have created at least one email account</strong>. Once its done, just run the following command to generate the signature:</p>
-<div class="highlight"><pre><span></span><code>./setup.sh config dkim
+<div class="highlight"><pre><span></span><code>./setup.sh<span class="w"> </span>config<span class="w"> </span>dkim
 </code></pre></div>
 <p>After generating DKIM keys, you should restart <code>docker-mailserver</code>. DNS edits may take a few minutes to hours to propagate.</p>
 <p>The script should ideally be run with a volume for <em>config</em> attached (eg: <code>./docker-data/dms/config/:/tmp/docker-mailserver/</code>), otherwise by default it will mount <code>./config/:/tmp/docker-mailserver/</code>.</p>
 <p>The default keysize when generating the signature is 4096 bits for now. If you need to change it (e.g. your DNS provider limits the size), then provide the size as the first parameter of the command:</p>
-<div class="highlight"><pre><span></span><code>./setup.sh config dkim keysize &lt;keysize&gt;
+<div class="highlight"><pre><span></span><code>./setup.sh<span class="w"> </span>config<span class="w"> </span>dkim<span class="w"> </span>keysize<span class="w"> </span>&lt;keysize&gt;
 </code></pre></div>
 <p>For LDAP systems that do not have any directly created user account you can run the following command (since <code>8.0.0</code>) to generate the signature by additionally providing the desired domain name (if you have multiple domains use the command multiple times or provide a comma-separated list of domains):</p>
-<div class="highlight"><pre><span></span><code>./setup.sh config dkim keysize &lt;key-size&gt; domain &lt;example.com&gt;<span class="o">[</span>,&lt;not-example.com&gt;<span class="o">]</span>
+<div class="highlight"><pre><span></span><code>./setup.sh<span class="w"> </span>config<span class="w"> </span>dkim<span class="w"> </span>keysize<span class="w"> </span>&lt;key-size&gt;<span class="w"> </span>domain<span class="w"> </span>&lt;example.com&gt;<span class="o">[</span>,&lt;not-example.com&gt;<span class="o">]</span>
 </code></pre></div>
 <p>Now the keys are generated, you can configure your DNS server with DKIM signature, simply by adding a TXT record. If you have direct access to your DNS zone file, then it's only a matter of pasting the content of <code>docker-data/dms/config/opendkim/keys/example.com/mail.txt</code> in your <code>example.com.hosts</code> zone.</p>

 <p>DMARC status is not being displayed instantly in Gmail for instance. If you want to check it directly after DNS entries, you can use some services around the Internet such as from <a href="https://dmarcguide.globalcyberalliance.org">Global Cyber Alliance</a> or <a href="https://ondmarc.redsift.com">RedSift</a>. In other cases, email clients will show "DMARC: PASS" in ~1 day or so.</p>

-<p>I spent HOURS trying to debug "Connection Refused" and "Connection closed by foreign host" errors when trying to use telnet to troubleshoot my connection. I was also trying to connect from my email client (macOS mail) around the same time. Telnet had also worked earlier, so I was extremely confused as to why it suddenly stopped working. I stumbled upon <code>fail2ban.log</code> in my container. In short, when trying to get my macOS client working, I exceeded the number of failed login attempts and fail2ban put dovecot and postfix in jail! I got around it by whitelisting my ipaddresses (my ec2 instance and my local computer)</p>

+<ol>
+<li><strong>Increase log verbosity</strong>: Very helpful for troubleshooting problems during container startup. Set the environment variable <a href="../environment/#log_level"><code>LOG_LEVEL</code></a> to <code>debug</code> or <code>trace</code>.</li>
+<li><strong>Use error logs as a search query</strong>: Try finding an <em>existing issue</em> or <em>search engine result</em> from any errors in your container log output. Often you'll find answers or more insights. If you still need to open an issue, sharing links from your search may help us assist you. The mail server log can be acquired by running <code>docker log &lt;CONTAINER NAME&gt;</code> (<em>or <code>docker logs -f &lt;CONTAINER NAME&gt;</code> if you want to follow the log</em>).</li>
+<li><strong>Understand the basics of mail servers</strong>: Especially for beginners, make sure you read our <a href="../../introduction/">Introduction</a> and <a href="../../usage/">Usage</a> articles.</li>
+<li><strong>Search the whole FAQ</strong>: Our <a href="../../faq/">FAQ</a> contains answers for common problems. Make sure you go through the list.</li>
+<li><strong>Reduce the scope</strong>: Ensure that you can run a basic setup of DMS first. Then incrementally restore parts of your original configuration until the problem is reproduced again. If you're new to DMS, it is common to find the cause is misunderstanding how to configure a minimal setup.</li>
+</ol>
+<h3 id="debug-a-running-container"><a class="toclink" href="#debug-a-running-container">Debug a running container</a></h3>
+<p>To get a shell inside the container run: <code>docker exec -it &lt;CONTAINER NAME&gt; bash</code>.</p>
+<p>If you need more flexibility than <code>docker logs</code> offers, within the container <code>/var/log/mail/mail.log</code> and <code>/var/log/supervisor/</code> are the most useful locations to get relevant DMS logs. Use the <code>tail</code> or <code>cat</code> commands to view their contents.</p>
+<p>To install additional software:</p>
+<ul>
+<li><code>apt-get update</code> is needed to update repository metadata.</li>
+<li><code>apt-get install &lt;PACKAGE&gt;</code></li>
+<li>For example if you need a text editor, <code>nano</code> is a good package choice for beginners.</li>

 <p>We recommend mounting the files directly into the container, as they are rather big and not manageable with the <a href="#with-the-help-of-a-custom-file">modules script</a>. If mounted to the correct location, Rspamd will automatically pick them up.</p>
 <p>While <em>Abusix</em> can be integrated into Postfix, Postscreen and a multitude of other software, we recommend integrating <em>Abusix</em> only into a single piece of software running in your mail server - everything else would be excessive and wasting queries. Moreover, we recommend the integration into suitable filtering software and not Postfix itself, as software like Postscreen or Rspamd can properly evaluate the return codes and other configuration.</p>

 <h2 id="custom-dh-parameters"><a class="toclink" href="#custom-dh-parameters">Custom DH Parameters</a></h2>
 <p>By default <code>docker-mailserver</code> uses <a href="https://github.com/internetstandards/dhe_groups"><code>ffdhe4096</code></a> from <a href="https://datatracker.ietf.org/doc/html/rfc7919">IETF RFC 7919</a>. These are standardized pre-defined DH groups and the only available DH groups for TLS 1.3. It is <a href="https://crypto.stackexchange.com/questions/29926/what-diffie-hellman-parameters-should-i-use">discouraged to generate your own DH parameters</a> as it is often less secure.</p>
 <p>Despite this, if you must use non-standard DH parameters or you would like to swap <code>ffdhe4096</code> for a different group (eg <code>ffdhe2048</code>); Add your own PEM encoded DH params file via a volume to <code>/tmp/docker-mailserver/dhparams.pem</code>. This will replace DH params for both Dovecot and Postfix services during container startup.</p>

+<summary>Beware of outdated advice on port 465</summary>
+<p>There is a common misconception of this port due to it's history detailed by various communities and blogs articles on the topic (<em>including by popular mail relay services</em>).</p>
+<p>Port 465 was <a href="https://en.wikipedia.org/wiki/SMTPS#History">briefly assigned the role of SMTPS in 1997</a> as an secure alternative to Port 25 between MTA exchanges. Then RFC 2487 (<code>STARTTLS</code>) <a href="https://web.archive.org/web/20150603202057/http://www.imc.org/ietf-apps-tls/mail-archive/msg00204.html">while still in a draft status in late 1998 had IANA revoke the SMTPS assignment</a>. The <a href="https://mailing.postfix.users.narkive.com/F3ACwg2F/which-port-to-use-for-ssl-tls#post21">draft history was modified to exclude all mention of port 465 and SMTPS</a>.</p>
+<p>In 2018 <a href="https://tools.ietf.org/html/rfc8314">RFC 8314</a> was published which revives Port 465 as an Implicit TLS alternative to Port 587 for mail submission. It details very clearly that gaining adoption of 465 as the preferred port will take time. IANA reassigned <a href="https://www.iana.org/assignments/service-names-port-numbers/service-names-port-numbers.xhtml?search=465">port 465 as the <code>submissions</code> service</a>. Any unofficial usage as <strong>SMTPS is legacy and has been for over two decades</strong>.</p>
+<p>Understand that port 587 is more broadly supported due to this history and that lots of software in that time has been built or configured with that port in mind. <a href="https://blog.apnic.net/2021/11/18/vulnerabilities-show-why-starttls-should-be-avoided-if-possible/"><code>STARTTLS</code> is known to have various CVEs discovered even in recent years</a>, do not be misled by any advice implying it should be preferred over implicit TLS. Trust in more official sources, such as the <a href="https://github.com/vdukhovni/postfix/blob/62931e5b1f9f1e80d02a496c7fd0062a5aae1d25/postfix/conf/master.cf#L38-L41">config Postfix has</a> which acknowledges the <code>submissions</code> port (465).</p>

-<li><strong>Port 465(<em>and 587</em>):</strong> This is the equivalent of a post office box where you would send email to be delivered on your behalf(<code>docker-mailserver</code> is that metaphorical post office, aka the MTA). Unlike port 25, these two ports are known as the <em>Submission</em> ports and require a valid email account on the server with a password to be able to send email to anyone outside of the server(an MTA you do not control, eg Outlook or Gmail).

+<p>When submitting mail (inbound) to be sent (outbound), this involves two separate connections to negotiate and secure. There may be additional intermediary connections which <code>docker-mailserver</code> is not involved in, and thus unable to ensure encrypted transit throughout delivery.</p>
+</div>
 <h4 id="outbound-traffic-on-the-right"><a class="toclink" href="#outbound-traffic-on-the-right">Outbound Traffic (On the Right)</a></h4>
+<p>Mail being sent from your server is either being relayed through another MTA (eg: SendGrid), or direct to an MTA responsible for an email address (eg: Gmail). </p>
 <ul>
-<li><strong>Port 25:</strong> Send the email directly to the given email address MTA as possible. Like your own <code>docker-mailserver</code> port 25, this is the standard port for receiving email on, thus email will almost always arrive to the final MTA on this port. Note that, there may be additional MTAs further in the chain, but this would be the public facing one representing that email address.</li>
-<li><strong>Port 465(<em>and 587</em>):</strong> SMTP Relays are a popular choice to hand-off delivery of email through. Services like SendGrid are useful for bulk email(marketing) or when your webhost or ISP are preventing you from using standard ports like port 25 to send out email(which can be abused by spammers). </li>
+<li><strong>Port 25:</strong><ul>
+<li>As most MTA use port 25 to receive inbound mail, when no authenticated relay is involved this is the outbound port used.</li>
+<li>Outbound traffic on this port is often blocked by service providers (eg: VPS, ISP) to prevent abuse by spammers. If the port cannot be unblocked, you will need to relay outbound mail through a service to send on your behalf.</li>
 </ul>
-<p><code>docker-mailserver</code> can serve as a relay too, but the difference between a DIY relay and a professional service is reputation, which is referenced by MTAs you're delivering to such as Outlook, Gmail or others(perhaps another <code>docker-mailserver</code> server!), when deciding if email should be marked as junked or potentially not delivered at all. As a service like SendGrid has a reputation to maintain, relay is restricted to registered users who must authenticate(even on port 25), they do not store email, merely forward it to another MTA which could be delivered on a different port like 25.</p>
+</li>
+<li><strong>Port 465 and 587:</strong><ul>
+<li>Submission ports for outbound traffic establish trust to forward mail through a third-party relay service. This requires <a href="../../advanced/mail-forwarding/relay-hosts/">authenticating to an account on the relay service</a>. The relay will then deliver the mail through port 25 on your behalf.</li>
+<li>These are the two typical ports used, but smart hosts like SendGrid often document support for additional non-standard ports as alternatives if necessary.</li>
+<li>Usually you'll only use these outbound ports for relaying. It is possible to deliver directly to the relevant MTA for email address, but requires having credentials for each MTA.</li>
+</ul>
+</li>
+</ul>
+<div class="admonition tip">
+<p class="admonition-title">Tip</p>
+<p><code>docker-mailserver</code> can function as a relay too, but professional relay services have a trusted reputation (<em>which increases success of delivery</em>).</p>
+<p>An MTA with low reputation can affect if mail is treated as junk, or even rejected.</p>

+<div class="admonition note">
+<p class="admonition-title">Note</p>
+<p>At best, you can only ensure a secure connection between the MTA you directly connect to. The receiving MTA may relay that mail to another MTA (<em>and so forth</em>), each connection may not be enforcing TLS.</p>

If both client and server support <code>STARTTLS</code> the connection will be secured over TLS, otherwise the connection is unable to use encryption to secure it.

-<p>Communication is always encrypted, avoiding the above mentioned issues with Explicit TLS.</p>
-<p>You may know of these ports as <strong>SMTPS, POP3S, IMAPS</strong>, which indicate the protocol in combination with a TLS connection. However, Explicit TLS ports provide the same benefit when <code>STARTTLS</code> is successfully negotiated; Implicit TLS better communicates the improved security to all three protocols (SMTP/POP3/IMAP over Implicit TLS).</p>
-<p>Additionally, referring to port 465 as <em>SMTPS</em> would be incorrect, as it is a submissions port requiring authentication to proceed via <em>ESMTP</em>, whereas ESMTPS has a different meaning(STARTTLS supported). Port 25 may lack Implicit TLS, but can be configured to be more secure between trusted parties via MTA-STS, STARTTLS Policy List, DNSSEC and DANE.</p>

 <h2 id="adding-a-new-account"><a class="toclink" href="#adding-a-new-account">Adding a New Account</a></h2>
 <p>Users (email accounts) are managed in <code>/tmp/docker-mailserver/postfix-accounts.cf</code>. <strong><em>The best way to manage accounts is to use the reliable <a href="../../setup.sh/"><code>setup.sh</code></a> script</em></strong>. Or you may directly add the <em>full</em> email address and its encrypted password, separated by a pipe:</p>

 <p>In the example above, we've added 2 mail accounts for 2 different domains. Consequently, the mail-server will automatically be configured for multi-domains. Therefore, to generate a new mail account data, directly from your docker host, you could for example run the following:</p>
-<div class="highlight"><pre><span></span><code>docker run --rm <span class="se">\</span>
-  -e <span class="nv">MAIL_USER</span><span class="o">=</span>user1@example.com <span class="se">\</span>
-  -e <span class="nv">MAIL_PASS</span><span class="o">=</span>mypassword <span class="se">\</span>
-  -it mailserver/docker-mailserver:latest <span class="se">\</span>
-  /bin/sh -c <span class="s1">&#39;echo &quot;$MAIL_USER|$(doveadm pw -s SHA512-CRYPT -u $MAIL_USER -p $MAIL_PASS)&quot;&#39;</span> &gt;&gt; docker-data/dms/config/postfix-accounts.cf
+<div class="highlight"><pre><span></span><code>docker<span class="w"> </span>run<span class="w"> </span>--rm<span class="w"> </span><span class="se">\</span>

 </code></pre></div>
 <p>You will then be asked for a password, and be given back the data for a new account entry, as text. To actually <em>add</em> this new account, just copy all the output text in <code>docker-data/dms/config/postfix-accounts.cf</code> file of your running container.</p>

 <p>A <strong>forward-only</strong> mail-server does not have any local mailboxes. Instead, it has only aliases that forward emails to external email accounts (for example to a Gmail account). You can also send email from the localhost (the computer where <code>docker-mailserver</code> is installed), using as sender any of the alias addresses.</p>
 <p>The important settings for this setup (on <code>mailserver.env</code>) are these:</p>

 <p>Since there are no local mailboxes, we use <code>SMTP_ONLY=1</code> to disable <code>dovecot</code>. We disable as well the other services that are related to local mailboxes (<code>POP3</code>, <code>ClamAV</code>, <code>SpamAssassin</code>, etc.)</p>
 <p>We can create aliases with <code>./setup.sh</code>, like this:</p>

 <h2 id="authenticating-with-ldap"><a class="toclink" href="#authenticating-with-ldap">Authenticating with LDAP</a></h2>
 <p>If you want to send emails from outside the mail-server you have to authenticate somehow (with a username and password). One way of doing it is described in <a href="https://github.com/docker-mailserver/docker-mailserver/issues/1247">this discussion</a>. However if there are many user accounts, it is better to use authentication with LDAP. The settings for this on <code>mailserver.env</code> are:</p>

-<div class="highlight"><pre><span></span><code><span class="na">add uid</span><span class="o">=</span><span class="s">username,ou=users,dc=example,dc=org</span><span class="w"></span>

 <p>This structure is different from what is expected/assumed from the configuration scripts of <code>docker-mailserver</code>, so it doesn't work just by using the <code>LDAP_QUERY_FILTER_...</code> settings. Instead, I had to use a custom configuration (<a href="../../../config/advanced/override-defaults/user-patches/">via <code>user-patches.sh</code></a>). I created the script <code>docker-data/dms/config/user-patches.sh</code>, with content like this:</p>

 <p>Suppose you want to change a number of settings that are not listed as variables or add things to the server that are not included?</p>
 <p><code>docker-mailserver</code> has a built-in way to do post-install processes. If you place a script called <strong><code>user-patches.sh</code></strong> in the config directory it will be run after all configuration files are set up, but before the postfix, amavis and other daemons are started.</p>
 <p>It is common to use a local directory for config added to <code>docker-mailsever</code> via a volume mount in your <code>docker-compose.yml</code> (eg: <code>./docker-data/dms/config/:/tmp/docker-mailserver/</code>).</p>
 <p>Add or create the script file to your config directory:</p>

 <p>Then fill <code>user-patches.sh</code> with suitable code.</p>

 <p>With the default settings, SpamAssassin will require 200 mails trained for spam (for example with the method explained above) and 200 mails trained for ham (using the same command as above but using <code>--ham</code> and providing it with some ham mails). Until you provided these 200+200 mails, SpamAssassin will not take the learned mails into account. For further reference, see the <a href="https://wiki.apache.org/spamassassin/BayesNotWorking">SpamAssassin Wiki</a>.</p>

 <p>The following components are required to create a <a href="https://en.wikipedia.org/wiki/Email_agent_(infrastructure)">complete delivery chain</a>:</p>
 <ul>
-<li>MUA: a <a href="https://en.wikipedia.org/wiki/Email_client">Mail User Agent</a> is basically any client/program capable of sending emails to a mail-server; while also capable of fetching emails from a mail-server for presenting them to the end users.</li>
-<li>MTA: a <a href="https://en.wikipedia.org/wiki/Message_transfer_agent">Mail Transfer Agent</a> is the so-called "mail-server" as seen from the MUA's perspective. It's a piece of software dedicated to accepting submitted emails, then forwarding them-where exactly will depend on an email's final destination. If the receiving MTA is responsible for the FQDN the email is sent to, then an MTA is to forward that email to an MDA (see below). Otherwise, it is to transfer (ie. forward, relay) to another MTA, "closer" to the email's final destination.</li>

+<summary>An Example</summary>
 <p>Let's say Alice owns a Gmail account, <code>alice@gmail.com</code>; and Bob owns an account on a <code>docker-mailserver</code>'s instance, <code>bob@dms.io</code>.</p>
 <p>Make sure not to conflate these two very different scenarios:
 A) Alice sends an email to <code>bob@dms.io</code> =&gt; the email is first submitted to MTA <code>smtp.gmail.com</code>, then relayed to MTA <code>smtp.dms.io</code> where it is then delivered into Bob's mailbox.
 B) Bob sends an email to <code>alice@gmail.com</code> =&gt; the email is first submitted to MTA <code>smtp.dms.io</code>, then relayed to MTA <code>smtp.gmail.com</code> and eventually delivered into Alice's mailbox.</p>
 <p>In scenario <em>A</em> the email leaves Gmail's premises, that email's <em>initial</em> submission is <em>not</em> handled by your <code>docker-mailserver</code> instance(MTA); it merely receives the email after it has been relayed by Gmail's MTA. In scenario <em>B</em>, the <code>docker-mailserver</code> instance(MTA) handles the submission, prior to relaying.</p>
 <p>The main takeaway is that when a third-party sends an email to a <code>docker-mailserver</code> instance(MTA) (or any MTA for that matter), it does <em>not</em> establish a direct connection with that MTA. Email submission first goes through the sender's MTA, then some relaying between at least two MTAs is required to deliver the email. That will prove very important when it comes to security management.</p>
-</div>
+</details>
 <p>One important thing to note is that MTA and MDA programs may actually handle <em>multiple</em> tasks (which is the case with <code>docker-mailserver</code>'s Postfix and Dovecot).</p>
-<p>For instance, Postfix is both an SMTP server (accepting emails) and a relaying MTA (transferring, ie. sending emails to other MTA/MDA); Dovecot is both an MDA (delivering emails in mailboxes) and an IMAP server (allowing MUAs to fetch emails from the <em>mail-server</em>). On top of that, Postfix may rely on Dovecot's authentication capabilities.</p>

On top of that, Postfix may rely on Dovecot's authentication capabilities.</p>
 <p>The exact relationship between all the components and their respective (sometimes shared) responsibilities is beyond the scope of this document. Please explore this wiki &amp; the web to get more insights about <code>docker-mailserver</code>'s toolchain.</p>

+<p>In the previous section, three components were outlined. Each one of those is responsible for a specific task when it comes to exchanging emails:</p>
 <ul>
-<li><em>Submission</em>: for a MUA (client), the act of sending actual email data over the network, toward an MTA (server).</li>
-<li><em>Transfer</em> (aka. <em>Relay</em>): for an MTA, the act of sending actual email data over the network, toward another MTA (server) closer to the final destination (where an MTA will forward data to an MDA).</li>
-<li><em>Retrieval</em>: for a MUA (client), the act of fetching actual email data over the network, from an MDA.</li>

 </ul>
-<p>Postfix handles Submission (and might handle Relay), whereas Dovecot handles Retrieval. They both need to be accessible by MUAs in order to act as servers, therefore they expose public endpoints on specific TCP ports (see. <a href="../config/security/understanding-the-ports/"><em>Understanding the ports</em></a> for more details). Those endpoints <em>may</em> be secured, using an encryption scheme and TLS certificates.</p>

 <p>When it comes to the specifics of email exchange, we have to look at protocols and ports enabled to support all the identified purposes. There are several valid options and they've been evolving overtime.</p>

-<h5 id="outward-submission"><a class="toclink" href="#outward-submission">Outward Submission</a></h5>
-<p>The best practice as of 2020 when it comes to securing Outward Submission is to use <em>Implicit TLS connection via ESMTP on port 465</em> (see <a href="https://tools.ietf.org/html/rfc8314">RFC 8314</a>). Let's break it down.</p>
-<ul>
-<li>Implicit TLS means the server <em>enforces</em> the client into using an encrypted TCP connection, using <a href="https://en.wikipedia.org/wiki/Transport_Layer_Security">TLS</a>. With this kind of connection, the MUA <em>has</em> to establish a TLS-encrypted connection from the get go (TLS is implied, hence the name "Implicit"). Any client attempting to either submit email in cleartext (unencrypted, not secure), or requesting a cleartext connection to be upgraded to a TLS-encrypted one using <code>STARTTLS</code>, is to be denied. Implicit TLS is sometimes called Enforced TLS for that reason.</li>
-<li><a href="https://en.wikipedia.org/wiki/ESMTP">ESMTP</a> is <a href="https://en.wikipedia.org/wiki/Simple_Mail_Transfer_Protocol">SMTP</a> + extensions. It's the version of the SMTP protocol that a mail-server commonly communicates with today. For the purpose of this documentation, ESMTP and SMTP are synonymous.</li>
-<li>Port 465 is the reserved TCP port for Implicit TLS Submission (since 2018). There is actually a boisterous history to that ports usage, but let's keep it simple.</li>
-</ul>
+<h4 id="outbound-submission"><a class="toclink" href="#outbound-submission">Outbound Submission</a></h4>
+<p>When it comes to securing Outbound Submission you should prefer to use <em>Implicit TLS connection via ESMTP on port 465</em> (see <a href="https://tools.ietf.org/html/rfc8314">RFC 8314</a>). Please read our article about <a href="../config/security/understanding-the-ports/"><strong>Understanding the Ports</strong></a> for more details!</p>
 <div class="admonition warning">
 <p class="admonition-title">Warning</p>
 <p>This Submission setup is sometimes referred to as <a href="https://en.wikipedia.org/wiki/SMTPS">SMTPS</a>. Long story short: this is incorrect and should be avoided.</p>
 </div>
 <p>Although a very satisfactory setup, Implicit TLS on port 465 is somewhat "cutting edge". There exists another well established mail Submission setup that must be supported as well, SMTP+STARTTLS on port 587. It uses Explicit TLS: the client starts with a cleartext connection, then the server informs a TLS-encrypted "upgraded" connection may be established, and the client <em>may</em> eventually decide to establish it prior to the Submission. Basically it's an opportunistic, opt-in TLS upgrade of the connection between the client and the server, at the client's discretion, using a mechanism known as <a href="https://en.wikipedia.org/wiki/Opportunistic_TLS">STARTTLS</a> that both ends need to implement.</p>
-<p>In many implementations, the mail-server doesn't enforce TLS encryption, for backwards compatibility. Clients are thus free to deny the TLS-upgrade proposal (or <a href="https://security.stackexchange.com/questions/168998/what-happens-if-starttls-dropped-in-smtp">misled by a hacker</a> about STARTTLS not being available), and the server accepts unencrypted (cleartext) mail exchange, which poses a confidentiality threat and, to some extent, spam issues. <a href="https://tools.ietf.org/html/rfc8314#section-3.3">RFC 8314 (section 3.3)</a> recommends for a mail-server to support both Implicit and Explicit TLS for Submission, <em>and</em> to enforce TLS-encryption on ports 587 (Explicit TLS) and 465 (Implicit TLS). That's exactly <code>docker-mailserver</code>'s default configuration: abiding by RFC 8314, it <a href="http://www.postfix.org/postconf.5.html#smtpd_tls_security_level">enforces a strict (<code>encrypt</code>) STARTTLS policy</a>, where a denied TLS upgrade terminates the connection thus (hopefully but at the client's discretion) preventing unencrypted (cleartext) Submission.</p>

 <p>The best practice as of 2020 is to enforce IMAPS on port 993, rather than IMAP+STARTTLS on port 143 (see <a href="https://tools.ietf.org/html/rfc8314">RFC 8314</a>); yet the latter is usually provided for backwards compatibility.</p>

 <ul>
 <li>Simple customization is supported through <a href="https://github.com/docker-mailserver/docker-mailserver/blob/master/docker-compose.yml">docker-compose configuration</a> and the <a href="https://github.com/docker-mailserver/docker-mailserver/blob/master/mailserver.env">env-mailserver</a> configuration file.</li>

 </ul>
-<p>On the subject of security, one might consider <code>docker-mailserver</code>'s <strong>default</strong> configuration to <em>not</em> be 100% secure:</p>
-<ul>
-<li>it enables unencrypted traffic on port 25</li>
-<li>it enables Explicit TLS (STARTTLS) on port 587, instead of Implicit TLS on port 465</li>
-</ul>
-<p>We believe <code>docker-mailserver</code>'s default configuration to be a good middle ground: it goes slightly beyond "old" (1999) <a href="https://tools.ietf.org/html/rfc2487">RFC 2487</a>; and with developer friendly configuration settings, it makes it pretty easy to abide by the "newest" (2018) <a href="https://tools.ietf.org/html/rfc8314">RFC 8314</a>.</p>
 <p>Eventually, it is up to <em>you</em> deciding exactly what kind of transportation/encryption to use and/or enforce, and to customize your instance accordingly (with looser or stricter security). Be also aware that protocols and ports on your server can only go so far with security; third-party MTAs might relay your emails on insecure connections, man-in-the-middle attacks might still prove effective, etc. Advanced counter-measure such as DANE, MTA-STS and/or full body encryption (eg. PGP) should be considered as well for increased confidentiality, but ideally without compromising backwards compatibility so as to not block emails.</p>

The filesystem is the database. This image is based on config files that can be persisted using bind mounts (default) or Docker volumes, and as such versioned, backed up and so forth. Where are emails stored? Mails are stored in /var/mail/${domain}/${username} . Since v9.0.0 it is possible to add custom user_attributes for each accounts to have a different mailbox configuration (See #1792 ). How are IMAP mailboxes ( aka IMAP Folders ) set up? INBOX is setup by default with the special IMAP folders Drafts , Sent , Junk and Trash . You can learn how to modify or add your own folders ( including additional special folders like Archive ) by visiting our docs page Customizing IMAP Folders for more information. How do I update DMS? Make sure to read the CHANGELOG before updating to new versions, to be prepared for possible breaking changes. Then, run the following commands: docker-compose pull docker-compose down docker-compose up -d You should see the new version number on startup, for example: [ INF ] Welcome to docker-mailserver 11.3.1 . And you're done! Don't forget to have a look at the remaining functions of the setup.sh script with ./setup.sh help . Which operating systems are supported? Linux is officially supported. Windows and macOS are not supported and users and have reported various issues running the image on these hosts. As you'll realistically be deploying to production on a Linux host, if you are on Windows or macOS and want to run the image locally first, it's advised to do so via a VM guest running Linux if you have issues running DMS on your host system. What are the system requirements? Recommended 1 vCore 2GB RAM Swap enabled for the container Minimum 1 vCore 512MB RAM You'll need to avoid running some services like ClamAV ( disabled by default ) to be able to run on a host with 512MB of RAM. Warning ClamAV can consume a lot of memory, as it reads the entire signature database into RAM. Current figure is about 850M and growing. If you get errors about ClamAV or amavis failing to allocate memory you need more RAM or more swap and of course docker must be allowed to use swap (not always the case). If you can't use swap at all you may need 3G RAM. How to alter a running DMS instance without relaunching the container? docker-mailserver aggregates multiple \"sub-services\", such as Postfix, Dovecot, Fail2ban, SpamAssassin, etc. In many cases, one may edit a sub-service's config and reload that very sub-service, without stopping and relaunching the whole mail-server. In order to do so, you'll probably want to push your config updates to your server through a Docker volume (these docs use: ./docker-data/dms/config/:/tmp/docker-mailserver/ ), then restart the sub-service to apply your changes, using supervisorctl . For instance, after editing fail2ban's config: supervisorctl restart fail2ban . See the documentation for supervisorctl . Tip To add, update or delete an email account; there is no need to restart postfix / dovecot service inside the container after using setup.sh script. For more information, see #1639 . How can I sync the container and host date/time? Share the host's /etc/localtime with the container, e.g. by using a bind mount: volumes : - /etc/localtime:/etc/localtime:ro Optionally, you can set the TZ ENV variable; e.g. TZ=Europe/Berlin . Check this list for which values are allowed. What is the file format? All files are using the Unix format with LF line endings. Please do not use CRLF . Do you support multiple domains? DMS supports multiple domains out of the box, so you can do this: ./setup.sh email add user1@example.com ./setup.sh email add user1@example.de ./setup.sh email add user1@server.example.org What about backups? Bind mounts (default) From the location of your docker-compose.yml , create a compressed archive of your docker-data/dms/config/ and docker-data/dms/mail-* folders: tar --gzip -cf \"backup- $( date +%F ) .tar.gz\" ./docker-data/dms Then to restore docker-data/dms/config/ and docker-data/dms/mail-* folders from your backup file: tar --gzip -xf backup-date.tar.gz Volumes Assuming that you use docker-compose and data volumes, you can backup the configuration, emails and logs like this: # create backup docker run --rm -it \\ -v \" ${ PWD } /docker-data/dms/config/:/tmp/docker-mailserver/\" \\ -v \" ${ PWD } /docker-data/dms-backups/:/backup/\" \\ --volumes-from mailserver \\ alpine:latest \\ tar czf \"/backup/mail- $( date +%F ) .tar.gz\" /var/mail /var/mail-state /var/log/mail /tmp/docker-mailserver # delete backups older than 30 days find \" ${ PWD } /docker-data/dms-backups/\" -type f -mtime +30 -delete What about the ./docker-data/dms/mail-state folder? When you run DMS with the ENV variable ONE_DIR=1 (default), this folder will: Provide support to persist Fail2Ban blocks, ClamAV signature updates, and the like when the container is restarted or recreated. To persist that container state properly this folder should be volume mounted to /var/mail-state/ internally . Service data is relocated to the mail-state folder for the following services: Postfix, Dovecot, Fail2Ban, Amavis, PostGrey, ClamAV, SpamAssassin. I Want to Know More About the Ports See this part of the documentation for further details and best practice advice, especially regarding security concerns . How can I configure my email client? Login is full email address ( <user>@<domain> ). # IMAP username : <user1@example.com> password : <mypassword> server : <mail.example.com> imap port : 143 or 993 with STARTTLS/SSL (recommended) imap path prefix : INBOX # SMTP smtp port : 25 or 587/465 with STARTTLS/SSL (recommended) username : <user1@example.com> password : <mypassword> DMS is properly configured for port 587, if possible, we recommend using port 465 for SMTP though. See this section to learn more about ports . Can I use a naked/bare domain (i.e. no hostname)? Yes, but not without some configuration changes. Normally it is assumed that DMS runs on a host with a name, so the fully qualified host name might be mail.example.com with the domain example.com . The MX records point to mail.example.com . To use a bare domain ( where the host name is example.com and the domain is also example.com ), change mydestination : From: mydestination = $myhostname, localhost.$mydomain, localhost To: mydestination = localhost.$mydomain, localhost Add the latter line to docker-data/dms/config/postfix-main.cf . If that doesn't work, make sure that OVERRIDE_HOSTNAME is blank in your mailserver.env file (see #1731 ). Without these changes there will be warnings in the logs like: warning: do not list domain example.com in BOTH mydestination and virtual_mailbox_domains Plus of course mail delivery fails. Also you need to define hostname: example.com in your docker-compose.yml and don't sepecify the domainname: at all. How can I configure a catch-all? Considering you want to redirect all incoming e-mails for the domain example.com to user1@example.com , add the following line to docker-data/dms/config/postfix-virtual.cf : @example.com user1@example.com How can I delete all the emails for a specific user? First of all, create a special alias named devnull by editing docker-data/dms/config/postfix-aliases.cf : devnull: /dev/null Considering you want to delete all the e-mails received for baduser@example.com , add the following line to docker-data/dms/config/postfix-virtual.cf : baduser@example.com devnull Important If you use a catch-all rule for the main/sub domain, you need another entry in docker-data/dms/config/postfix-virtual.cf : @mail.example.com hello@example.com baduser@example.com devnull devnull@mail.example.com devnull What kind of SSL certificates can I use? Both RSA and ECDSA certs are supported. You can provide your own cert files manually, or mount a letsencrypt generated directory ( with alternative support for Traefik's acme.json ). Check out the SSL_TYPE documentation for more details. I just moved from my old mail server to DMS, but \"it doesn't work\"? If this migration implies a DNS modification, be sure to wait for DNS propagation before opening an issue. Few examples of symptoms can be found here or here . This could be related to a modification of your MX record, or the IP mapped to mail.example.com . Additionally, validate your DNS configuration . If everything is OK regarding DNS, please provide formatted logs and config files. This will allow us to help you. If we're blind, we won't be able to do anything. Can DMS run in a Rancher environment? Yes, by adding the environment variable PERMIT_DOCKER: network . Warning Adding the Docker network's gateway to the list of trusted hosts, e.g. using the network or connected-networks option, can create an open relay , for instance if IPv6 is enabled on the host machine but not in Docker . How can I authenticate users with SMTP_ONLY=1 ? See #1247 for an example. Todo Write a How-to / Use-Case / Tutorial about authentication with SMTP_ONLY . Common Errors warning: connect to Milter service inet:localhost:8893: Connection refused # DMARC not running # = > /etc/init.d/opendmarc restart warning: connect to Milter service inet:localhost:8891: Connection refused # DKIM not running # = > /etc/init.d/opendkim restart mail amavis[1459]: (01459-01) (!)connect to /var/run/clamav/clamd.ctl failed, attempt #1: Can't connect to a UNIX socket /var/run/clamav/clamd.ctl: No such file or directory mail amavis[1459]: (01459-01) (!)ClamAV-clamd: All attempts (1) failed connecting to /var/run/clamav/clamd.ctl, retrying (2) mail amavis[1459]: (01459-01) (!)ClamAV-clamscan av-scanner FAILED: /usr/bin/clamscan KILLED, signal 9 (0009) at (eval 100) line 905. mail amavis[1459]: (01459-01) (!!)AV: ALL VIRUS SCANNERS FAILED # Clamav is not running ( not started or because you don ' t have enough memory ) # = > check requirements and/or start Clamav How to use DMS behind a proxy Using user-patches.sh , update the container file /etc/postfix/main.cf to include: proxy_interfaces = X.X.X.X (your public IP) How to adjust settings with the user-patches.sh script Suppose you want to change a number of settings that are not listed as variables or add things to the server that are not included? docker-mailserver has a built-in way to do post-install processes. If you place a script called user-patches.sh in the config directory it will be run after all configuration files are set up, but before the postfix, amavis and other daemons are started. It is common to use a local directory for config added to docker-mailsever via a volume mount in your docker-compose.yml (eg: ./docker-data/dms/config/:/tmp/docker-mailserver/ ). Add or create the script file to your config directory: cd ./docker-data/dms/config touch user-patches.sh chmod +x user-patches.sh Then fill user-patches.sh with suitable code. If you want to test it you can move into the running container, run it and see if it does what you want. For instance: # start shell in container ./setup.sh debug login # check the file cat /tmp/docker-mailserver/user-patches.sh # run the script /tmp/docker-mailserver/user-patches.sh # exit the container shell back to the host shell exit You can do a lot of things with such a script. You can find an example user-patches.sh script here: example user-patches.sh script . We also have a very similar docs page specifically about this feature! Special use-case - patching the supervisord configuration It seems worth noting, that the user-patches.sh gets executed through supervisord . If you need to patch some supervisord config (e.g. /etc/supervisor/conf.d/saslauth.conf ), the patching happens too late. An easy workaround is to make the user-patches.sh reload the supervisord config after patching it: #!/bin/bash sed -i 's/rimap -r/rimap/' /etc/supervisor/conf.d/saslauth.conf supervisorctl update How to ban custom IP addresses with Fail2ban Use the following command: ./setup.sh fail2ban ban <IP> The default bantime is 180 days. This value can be customized . What to do in case of SPF/Forwarding problems If you got any problems with SPF and/or forwarding mails, give SRS a try. You enable SRS by setting ENABLE_SRS=1 . See the variable description for further information. Why are my emails not being delivered? There are many reasons why email might be rejected, common causes are: Wrong or untrustworthy SSL certificate. A TLD (your domain) or IP address with a bad reputation. Misconfigured DNS records. DMS does not manage those concerns, verify they are not causing your delivery problems before reporting a bug on our issue tracker. Resources that can help you troubleshoot: mail-tester can test your deliverability. helloinbox provides a checklist of things to improve your deliverability. SpamAssasin How can I manage my custom SpamAssassin rules? Antispam rules are managed in docker-data/dms/config/spamassassin-rules.cf . What are acceptable SA_SPAM_SUBJECT values? For no subject set SA_SPAM_SUBJECT=undef . For a trailing white-space subject one can define the whole variable with quotes in docker-compose.yml : environment : - \"SA_SPAM_SUBJECT=[SPAM] \" Why are SpamAssassin x-headers not inserted into my subdomain.example.com subdomain emails? In the default setup, amavis only applies SpamAssassin x-headers into domains matching the template listed in the config file ( 05-domain_id in the amavis defaults). The default setup @local_domains_acl = ( \".$mydomain\" ); does not match subdomains. To match subdomains, you can override the @local_domains_acl directive in the amavis user config file 50-user with @local_domains_maps = (\".\"); to match any sort of domain template. How can I make SpamAssassin better recognize spam? Put received spams in .Junk/ imap folder using SPAMASSASSIN_SPAM_TO_INBOX=1 and MOVE_SPAM_TO_JUNK=1 and add a user cron like the following: # This assumes you're having `environment: ONE_DIR=1` in the `mailserver.env`, # with a consolidated config in `/var/mail-state` # # m h dom mon dow command # Everyday 2:00AM, learn spam from a specific user 0 2 * * * docker exec mailserver sa-learn --spam /var/mail/example.com/username/.Junk --dbpath /var/mail-state/lib-amavis/.spamassassin With docker-compose you can more easily use the internal instance of cron within docker-mailserver . This is less problematic than the simple solution shown above, because it decouples the learning from the host on which docker-mailserver is running, and avoids errors if the mail-server is not running. The following configuration works nicely: Example Create a system cron file: # in the docker-compose.yml root directory mkdir -p ./docker-data/dms/cron touch ./docker-data/dms/cron/sa-learn chown root:root ./docker-data/dms/cron/sa-learn chmod 0644 ./docker-data/dms/cron/sa-learn Edit the system cron file nano ./docker-data/dms/cron/sa-learn , and set an appropriate configuration: # This assumes you're having `environment: ONE_DIR=1` in the env-mailserver, # with a consolidated config in `/var/mail-state` # # '> /dev/null' to send error notifications from 'stderr' to 'postmaster@example.com' # # m h dom mon dow user command # # Everyday 2:00AM, learn spam from a specific user # spam: junk directory 0 2 * * * root sa-learn --spam /var/mail/example.com/username/.Junk --dbpath /var/mail-state/lib-amavis/.spamassassin > /dev/null # ham: archive directories 15 2 * * * root sa-learn --ham /var/mail/example.com/username/.Archive* --dbpath /var/mail-state/lib-amavis/.spamassassin > /dev/null # ham: inbox subdirectories 30 2 * * * root sa-learn --ham /var/mail/example.com/username/cur* --dbpath /var/mail-state/lib-amavis/.spamassassin > /dev/null # # Everyday 3:00AM, learn spam from all users of a domain # spam: junk directory 0 3 * * * root sa-learn --spam /var/mail/not-example.com/*/.Junk --dbpath /var/mail-state/lib-amavis/.spamassassin > /dev/null # ham: archive directories 15 3 * * * root sa-learn --ham /var/mail/not-example.com/*/.Archive* --dbpath /var/mail-state/lib-amavis/.spamassassin > /dev/null # ham: inbox subdirectories 30 3 * * * root sa-learn --ham /var/mail/not-example.com/*/cur* --dbpath /var/mail-state/lib-amavis/.spamassassin > /dev/null Then with docker-compose.yml : services : mailserver : image : docker.io/mailserver/docker-mailserver:latest volumes : - ./docker-data/dms/cron/sa-learn:/etc/cron.d/sa-learn Or with Docker Swarm : version : '3.8' services : mailserver : image : docker.io/mailserver/docker-mailserver:latest # ... configs : - source : my_sa_crontab target : /etc/cron.d/sa-learn configs : my_sa_crontab : file : ./docker-data/dms/cron/sa-learn With the default settings, SpamAssassin will require 200 mails trained for spam (for example with the method explained above) and 200 mails trained for ham (using the same command as above but using --ham and providing it with some ham mails). Until you provided these 200+200 mails, SpamAssassin will not take the learned mails into account. For further reference, see the SpamAssassin Wiki . How do I have more control about what SpamAssassin is filtering? By default, SPAM and INFECTED emails are put to a quarantine which is not very straight forward to access. Several config settings are affecting this behavior: First, make sure you have the proper thresholds set: SA_TAG = -100000.0 SA_TAG2 = 3.75 SA_KILL = 100000.0 The very negative vaue in SA_TAG makes sure, that all emails have the SpamAssassin headers included. SA_TAG2 is the actual threshold to set the YES/NO flag for spam detection. SA_KILL needs to be very high, to make sure nothing is bounced at all ( SA_KILL superseeds SPAMASSASSIN_SPAM_TO_INBOX ) Make sure everything (including SPAM) is delivered to the inbox and not quarantined: SPAMASSASSIN_SPAM_TO_INBOX = 1 Use MOVE_SPAM_TO_JUNK=1 or create a sieve script which puts spam to the Junk folder: require [ \"comparator-i;ascii-numeric\" , \"relational\" , \"fileinto\" ]; if header :contains \"X-Spam-Flag\" \"YES\" { fileinto \"Junk\" ; } elsif allof ( not header :matches \"x-spam-score\" \"-*\" , header :value \"ge\" :comparator \"i;ascii-numeric\" \"x-spam-score\" \"3.75\" ) { fileinto \"Junk\" ; } Create a dedicated mailbox for emails which are infected/bad header and everything amavis is blocking by default and put its address into docker-data/dms/config/amavis.cf $clean_quarantine_to = \"amavis\\@example.com\"; $virus_quarantine_to = \"amavis\\@example.com\"; $banned_quarantine_to = \"amavis\\@example.com\"; $bad_header_quarantine_to = \"amavis\\@example.com\"; $spam_quarantine_to = \"amavis\\@example.com\";","title":"FAQ"},{"location":"faq/#what-kind-of-database-are-you-using","text":"None!

It is common to use a local directory for config added to docker-mailsever via a volume mount in your docker-compose.yml (eg: ./docker-data/dms/config/:/tmp/docker-mailserver/ ). Add or create the script file to your config directory: cd ./docker-data/dms/config touch user-patches.sh chmod +x user-patches.sh Then fill user-patches.sh with suitable code.

Here's an introduction to the field that covers everything you need to know to get started with docker-mailserver . Anatomy of a Mail-Server A mail-server is only a part of a client-server relationship aimed at exchanging information in the form of emails . Exchanging emails requires using specific means (programs and protocols). docker-mailserver provides you with the server portion, whereas the client can be anything from a terminal via text-based software (eg. Mutt ) to a fully-fledged desktop application (eg. Mozilla Thunderbird , Microsoft Outlook \u2026), to a web interface, etc. Unlike the client-side where usually a single program is used to perform retrieval and viewing of emails, the server-side is composed of many specialized components. The mail-server is capable of accepting, forwarding, delivering, storing and overall exchanging messages, but each one of those tasks is actually handled by a specific piece of software. All of these \"agents\" must be integrated with one another for the exchange to take place. docker-mailserver has made informed choices about those components and their (default) configuration. It offers a comprehensive platform to run a fully featured mail-server in no time! Components The following components are required to create a complete delivery chain : MUA: a Mail User Agent is basically any client/program capable of sending emails to a mail-server; while also capable of fetching emails from a mail-server for presenting them to the end users. MTA: a Mail Transfer Agent is the so-called \"mail-server\" as seen from the MUA's perspective. It's a piece of software dedicated to accepting submitted emails, then forwarding them-where exactly will depend on an email's final destination. If the receiving MTA is responsible for the FQDN the email is sent to, then an MTA is to forward that email to an MDA (see below). Otherwise, it is to transfer (ie. forward, relay) to another MTA, \"closer\" to the email's final destination. MDA: a Mail Delivery Agent is responsible for accepting emails from an MTA and dropping them into their recipients' mailboxes, whichever the form. Here's a schematic view of mail delivery: Sending an email: MUA ----> MTA ----> (MTA relays) ----> MDA Fetching an email: MUA <--------------------------------- MDA There may be other moving parts or sub-divisions (for instance, at several points along the chain, specialized programs may be analyzing, filtering, bouncing, editing\u2026 the exchanged emails). In a nutshell, docker-mailserver provides you with the following components: A MTA: Postfix A MDA: Dovecot A bunch of additional programs to improve security and emails processing Here's where docker-mailserver 's toochain fits within the delivery chain: docker-mailserver is here: \u250f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2513 Sending an email: MUA ---> MTA ---> (MTA relays) ---> \u252b MTA \u256e \u2503 Fetching an email: MUA <------------------------------ \u252b MDA \u256f \u2503 \u2517\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u251b Example Let's say Alice owns a Gmail account, alice@gmail.com ; and Bob owns an account on a docker-mailserver 's instance, bob@dms.io . Make sure not to conflate these two very different scenarios: A) Alice sends an email to bob@dms.io => the email is first submitted to MTA smtp.gmail.com , then relayed to MTA smtp.dms.io where it is then delivered into Bob's mailbox. B) Bob sends an email to alice@gmail.com => the email is first submitted to MTA smtp.dms.io , then relayed to MTA smtp.gmail.com and eventually delivered into Alice's mailbox. In scenario A the email leaves Gmail's premises, that email's initial submission is not handled by your docker-mailserver instance(MTA); it merely receives the email after it has been relayed by Gmail's MTA. In scenario B , the docker-mailserver instance(MTA) handles the submission, prior to relaying. The main takeaway is that when a third-party sends an email to a docker-mailserver instance(MTA) (or any MTA for that matter), it does not establish a direct connection with that MTA. Email submission first goes through the sender's MTA, then some relaying between at least two MTAs is required to deliver the email. That will prove very important when it comes to security management. One important thing to note is that MTA and MDA programs may actually handle multiple tasks (which is the case with docker-mailserver 's Postfix and Dovecot). For instance, Postfix is both an SMTP server (accepting emails) and a relaying MTA (transferring, ie. sending emails to other MTA/MDA); Dovecot is both an MDA (delivering emails in mailboxes) and an IMAP server (allowing MUAs to fetch emails from the mail-server ). On top of that, Postfix may rely on Dovecot's authentication capabilities. The exact relationship between all the components and their respective (sometimes shared) responsibilities is beyond the scope of this document. Please explore this wiki & the web to get more insights about docker-mailserver 's toolchain. About Security & Ports In the previous section, different components were outlined. Each one of those is responsible for a specific task, it has a specific purpose. Three main purposes exist when it comes to exchanging emails: Submission : for a MUA (client), the act of sending actual email data over the network, toward an MTA (server). Transfer (aka. Relay ): for an MTA, the act of sending actual email data over the network, toward another MTA (server) closer to the final destination (where an MTA will forward data to an MDA). Retrieval : for a MUA (client), the act of fetching actual email data over the network, from an MDA. Postfix handles Submission (and might handle Relay), whereas Dovecot handles Retrieval. They both need to be accessible by MUAs in order to act as servers, therefore they expose public endpoints on specific TCP ports (see. Understanding the ports for more details). Those endpoints may be secured, using an encryption scheme and TLS certificates.

Read on to expand your understanding and learn about docker-mailserver 's configuration, including how you can customize it. Submission - SMTP For a MUA to send an email to an MTA, it needs to establish a connection with that server, then push data packets over a network that both the MUA (client) and the MTA (server) are connected to. The server implements the SMTP protocol, which makes it capable of handling Submission . In the case of docker-mailserver , the MTA (SMTP server) is Postfix. The MUA (client) may vary, yet its Submission request is performed as TCP packets sent over the public internet. This exchange of information may be secured in order to counter eavesdropping. Two kinds of Submission Let's say I own an account on a docker-mailserver instance, me@dms.io . There are two very different use-cases for Submission: I want to send an email to someone Someone wants to send you an email In the first scenario, I will be submitting my email directly to my docker-mailserver instance/MTA (Postfix), which will then relay the email to its recipient's MTA for final delivery. In this case, Submission is first handled by establishing a direct connection to my own MTA-so at least for this portion of the delivery chain, I'll be able to ensure security/confidentiality. Not so much for what comes next, ie. relaying between MTAs and final delivery. In the second scenario, a third-party email account owner will be first submitting an email to some third-party MTA. I have no control over this initial portion of the delivery chain, nor do I have control over the relaying that comes next. My MTA will merely accept a relayed email coming \"out of the blue\". My MTA will thus have to support two kinds of Submission: Outward Submission (self-owned email is submitted directly to the MTA, then is relayed \"outside\") Inward Submission (third-party email has been submitted & relayed, then is accepted \"inside\" by the MTA) \u250f\u2501\u2501\u2501\u2501 Outward Submission \u2501\u2501\u2501\u2501\u2513 \u250c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2510 \u250c\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2510 Me ---------------> \u2524 \u251c -----------------> \u250a \u250a \u2502 My MTA \u2502 \u250a Third-party MTA \u250a \u2502 \u251c <----------------- \u250a \u250a \u2514\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2518 \u2514\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2518 \u2517\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501 Inward Submission \u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u251b Outward Submission The best practice as of 2020 when it comes to securing Outward Submission is to use Implicit TLS connection via ESMTP on port 465 (see RFC 8314 ). Let's break it down. Implicit TLS means the server enforces the client into using an encrypted TCP connection, using TLS . With this kind of connection, the MUA has to establish a TLS-encrypted connection from the get go (TLS is implied, hence the name \"Implicit\"). Any client attempting to either submit email in cleartext (unencrypted, not secure), or requesting a cleartext connection to be upgraded to a TLS-encrypted one using STARTTLS , is to be denied. Implicit TLS is sometimes called Enforced TLS for that reason. ESMTP is SMTP + extensions. It's the version of the SMTP protocol that a mail-server commonly communicates with today. For the purpose of this documentation, ESMTP and SMTP are synonymous. Port 465 is the reserved TCP port for Implicit TLS Submission (since 2018). There is actually a boisterous history to that ports usage, but let's keep it simple. Warning This Submission setup is sometimes referred to as SMTPS . Long story short: this is incorrect and should be avoided. Although a very satisfactory setup, Implicit TLS on port 465 is somewhat \"cutting edge\". There exists another well established mail Submission setup that must be supported as well, SMTP+STARTTLS on port 587. It uses Explicit TLS: the client starts with a cleartext connection, then the server informs a TLS-encrypted \"upgraded\" connection may be established, and the client may eventually decide to establish it prior to the Submission. Basically it's an opportunistic, opt-in TLS upgrade of the connection between the client and the server, at the client's discretion, using a mechanism known as STARTTLS that both ends need to implement. In many implementations, the mail-server doesn't enforce TLS encryption, for backwards compatibility. Clients are thus free to deny the TLS-upgrade proposal (or misled by a hacker about STARTTLS not being available), and the server accepts unencrypted (cleartext) mail exchange, which poses a confidentiality threat and, to some extent, spam issues. RFC 8314 (section 3.3) recommends for a mail-server to support both Implicit and Explicit TLS for Submission, and to enforce TLS-encryption on ports 587 (Explicit TLS) and 465 (Implicit TLS). That's exactly docker-mailserver 's default configuration: abiding by RFC 8314, it enforces a strict ( encrypt ) STARTTLS policy , where a denied TLS upgrade terminates the connection thus (hopefully but at the client's discretion) preventing unencrypted (cleartext) Submission. docker-mailserver 's default configuration enables and requires Explicit TLS (STARTTLS) on port 587 for Outward Submission. It does not enable Implicit TLS Outward Submission on port 465 by default. One may enable it through simple custom configuration, either as a replacement or (better!) supplementary mean of secure Submission. It does not support old MUAs (clients) not supporting TLS encryption on ports 587/465 (those should perform Submission on port 25, more details below). One may relax that constraint through advanced custom configuration, for backwards compatibility. A final Outward Submission setup exists and is akin SMTP+STARTTLS on port 587, but on port 25. That port has historically been reserved specifically for unencrypted (cleartext) mail exchange though, making STARTTLS a bit wrong to use. As is expected by RFC 5321 , docker-mailserver uses port 25 for unencrypted Submission in order to support older clients, but most importantly for unencrypted Transfer/Relay between MTAs. docker-mailserver 's default configuration also enables unencrypted (cleartext) on port 25 for Outward Submission. It does not enable Explicit TLS (STARTTLS) on port 25 by default. One may enable it through advanced custom configuration, either as a replacement (bad!) or as a supplementary mean of secure Outward Submission. One may also secure Outward Submission using advanced encryption scheme, such as DANE/DNSSEC and/or MTA-STS. Inward Submission Granted it's still very difficult enforcing encryption between MTAs (Transfer/Relay) without risking dropping emails (when relayed by MTAs not supporting TLS-encryption), Inward Submission is to be handled in cleartext on port 25 by default. docker-mailserver 's default configuration enables unencrypted (cleartext) on port 25 for Inward Submission. It does not enable Explicit TLS (STARTTLS) on port 25 by default. One may enable it through advanced custom configuration, either as a replacement (bad!) or as a supplementary mean of secure Inward Submission. One may also secure Inward Submission using advanced encryption scheme, such as DANE/DNSSEC and/or MTA-STS. Overall, docker-mailserver 's default configuration for SMTP looks like this: \u250f\u2501\u2501\u2501\u2501 Outward Submission \u2501\u2501\u2501\u2501\u2513 \u250c\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2510 \u250c\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2510 Me -- cleartext --> \u2524(25) (25)\u251c --- cleartext ---> \u250a \u250a Me -- STARTTLS ---> \u2524(587) My MTA \u2502 \u250a Third-party MTA \u250a \u2502 (25)\u251c <---cleartext ---- \u250a \u250a \u2514\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2518 \u2514\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2504\u2518 \u2517\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501 Inward Submission \u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u251b Retrieval - IMAP A MUA willing to fetch an email from a mail-server will most likely communicate with its IMAP server. As with SMTP described earlier, communication will take place in the form of data packets exchanged over a network that both the client and the server are connected to. The IMAP protocol makes the server capable of handling Retrieval . In the case of docker-mailserver , the IMAP server is Dovecot. The MUA (client) may vary, yet its Retrieval request is performed as TCP packets sent over the public internet. This exchange of information may be secured in order to counter eavesdropping. Again, as with SMTP described earlier, the IMAP protocol may be secured with either Implicit TLS (aka. IMAPS / IMAP4S) or Explicit TLS (using STARTTLS). The best practice as of 2020 is to enforce IMAPS on port 993, rather than IMAP+STARTTLS on port 143 (see RFC 8314 ); yet the latter is usually provided for backwards compatibility. docker-mailserver 's default configuration enables both Implicit and Explicit TLS for Retrievial, on ports 993 and 143 respectively. Retrieval - POP3 Similarly to IMAP, the older POP3 protocol may be secured with either Implicit or Explicit TLS. The best practice as of 2020 would be POP3S on port 995, rather than POP3 +STARTTLS on port 110 (see RFC 8314 ). docker-mailserver 's default configuration disables POP3 altogether. One should expect MUAs to use TLS-encrypted IMAP for Retrieval. How does docker-mailserver help with setting everything up? As a batteries included Docker image, docker-mailserver provides you with all the required components and a default configuration, to run a decent and secure mail-server. One may then customize all aspects of its internal components. Simple customization is supported through docker-compose configuration and the env-mailserver configuration file. Advanced customization is supported through providing \"monkey-patching\" configuration files and/or deriving your own image from docker-mailserver 's upstream, for a complete control over how things run. On the subject of security, one might consider docker-mailserver 's default configuration to not be 100% secure: it enables unencrypted traffic on port 25 it enables Explicit TLS (STARTTLS) on port 587, instead of Implicit TLS on port 465 We believe docker-mailserver 's default configuration to be a good middle ground: it goes slightly beyond \"old\" (1999) RFC 2487 ; and with developer friendly configuration settings, it makes it pretty easy to abide by the \"newest\" (2018) RFC 8314 . Eventually, it is up to you deciding exactly what kind of transportation/encryption to use and/or enforce, and to customize your instance accordingly (with looser or stricter security). Be also aware that protocols and ports on your server can only go so far with security; third-party MTAs might relay your emails on insecure connections, man-in-the-middle attacks might still prove effective, etc. Advanced counter-measure such as DANE, MTA-STS and/or full body encryption (eg. PGP) should be considered as well for increased confidentiality, but ideally without compromising backwards compatibility so as to not block emails. The README is the best starting point in configuring and running your mail-server. You may then explore this wiki to cover additional topics, including but not limited to, security.","title":"Introduction"},{"location":"introduction/#anatomy-of-a-mail-server","text":"A mail-server is only a part of a client-server relationship aimed at exchanging information in the form of emails . Exchanging emails requires using specific means (programs and protocols). docker-mailserver provides you with the server portion, whereas the client can be anything from a terminal via text-based software (eg. Mutt ) to a fully-fledged desktop application (eg. Mozilla Thunderbird , Microsoft Outlook \u2026), to a web interface, etc. Unlike the client-side where usually a single program is used to perform retrieval and viewing of emails, the server-side is composed of many specialized components. The mail-server is capable of accepting, forwarding, delivering, storing and overall exchanging messages, but each one of those tasks is actually handled by a specific piece of software. All of these \"agents\" must be integrated with one another for the exchange to take place. docker-mailserver has made informed choices about those components and their (default) configuration. It offers a comprehensive platform to run a fully featured mail-server in no time!","title":"Anatomy of a Mail-Server"},{"location":"introduction/#components","text":"The following components are required to create a complete delivery chain : MUA: a Mail User Agent is basically any client/program capable of sending emails to a mail-server; while also capable of fetching emails from a mail-server for presenting them to the end users. MTA: a Mail Transfer Agent is the so-called \"mail-server\" as seen from the MUA's perspective. It's a piece of software dedicated to accepting submitted emails, then forwarding them-where exactly will depend on an email's final destination. If the receiving MTA is responsible for the FQDN the email is sent to, then an MTA is to forward that email to an MDA (see below). Otherwise, it is to transfer (ie. forward, relay) to another MTA, \"closer\" to the email's final destination. MDA: a Mail Delivery Agent is responsible for accepting emails from an MTA and dropping them into their recipients' mailboxes, whichever the form. Here's a schematic view of mail delivery: Sending an email: MUA ----> MTA ----> (MTA relays) ----> MDA Fetching an email: MUA <--------------------------------- MDA There may be other moving parts or sub-divisions (for instance, at several points along the chain, specialized programs may be analyzing, filtering, bouncing, editing\u2026 the exchanged emails). In a nutshell, docker-mailserver provides you with the following components: A MTA: Postfix A MDA: Dovecot A bunch of additional programs to improve security and emails processing Here's where docker-mailserver 's toochain fits within the delivery chain: docker-mailserver is here: \u250f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2513 Sending an email: MUA ---> MTA ---> (MTA relays) ---> \u252b MTA \u256e \u2503 Fetching an email: MUA <------------------------------ \u252b MDA \u256f \u2503 \u2517\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u251b Example Let's say Alice owns a Gmail account, alice@gmail.com ; and Bob owns an account on a docker-mailserver 's instance, bob@dms.io . Make sure not to conflate these two very different scenarios: A) Alice sends an email to bob@dms.io => the email is first submitted to MTA smtp.gmail.com , then relayed to MTA smtp.dms.io where it is then delivered into Bob's mailbox. B) Bob sends an email to alice@gmail.com => the email is first submitted to MTA smtp.dms.io , then relayed to MTA smtp.gmail.com and eventually delivered into Alice's mailbox. In scenario A the email leaves Gmail's premises, that email's initial submission is not handled by your docker-mailserver instance(MTA); it merely receives the email after it has been relayed by Gmail's MTA. In scenario B , the docker-mailserver instance(MTA) handles the submission, prior to relaying. The main takeaway is that when a third-party sends an email to a docker-mailserver instance(MTA) (or any MTA for that matter), it does not establish a direct connection with that MTA. Email submission first goes through the sender's MTA, then some relaying between at least two MTAs is required to deliver the email. That will prove very important when it comes to security management. One important thing to note is that MTA and MDA programs may actually handle multiple tasks (which is the case with docker-mailserver 's Postfix and Dovecot). For instance, Postfix is both an SMTP server (accepting emails) and a relaying MTA (transferring, ie. sending emails to other MTA/MDA); Dovecot is both an MDA (delivering emails in mailboxes) and an IMAP server (allowing MUAs to fetch emails from the mail-server ). On top of that, Postfix may rely on Dovecot's authentication capabilities. The exact relationship between all the components and their respective (sometimes shared) responsibilities is beyond the scope of this document. Please explore this wiki & the web to get more insights about docker-mailserver 's toolchain.","title":"Components"},{"location":"introduction/#about-security-ports","text":"In the previous section, different components were outlined. Each one of those is responsible for a specific task, it has a specific purpose. Three main purposes exist when it comes to exchanging emails: Submission : for a MUA (client), the act of sending actual email data over the network, toward an MTA (server). Transfer (aka. Relay ): for an MTA, the act of sending actual email data over the network, toward another MTA (server) closer to the final destination (where an MTA will forward data to an MDA). Retrieval : for a MUA (client), the act of fetching actual email data over the network, from an MDA. Postfix handles Submission (and might handle Relay), whereas Dovecot handles Retrieval. They both need to be accessible by MUAs in order to act as servers, therefore they expose public endpoints on specific TCP ports (see. Understanding the ports for more details).

There are two very different use-cases for Submission: I want to send an email to someone Someone wants to send you an email In the first scenario, I will be submitting my email directly to my docker-mailserver instance/MTA (Postfix), which will then relay the email to its recipient's MTA for final delivery. In this case, Submission is first handled by establishing a direct connection to my own MTA-so at least for this portion of the delivery chain, I'll be able to ensure security/confidentiality. Not so much for what comes next, ie. relaying between MTAs and final delivery. In the second scenario, a third-party email account owner will be first submitting an email to some third-party MTA. I have no control over this initial portion of the delivery chain, nor do I have control over the relaying that comes next. My MTA will merely accept a relayed email coming \"out of the blue\".

Let's break it down. Implicit TLS means the server enforces the client into using an encrypted TCP connection, using TLS . With this kind of connection, the MUA has to establish a TLS-encrypted connection from the get go (TLS is implied, hence the name \"Implicit\"). Any client attempting to either submit email in cleartext (unencrypted, not secure), or requesting a cleartext connection to be upgraded to a TLS-encrypted one using STARTTLS , is to be denied. Implicit TLS is sometimes called Enforced TLS for that reason. ESMTP is SMTP + extensions. It's the version of the SMTP protocol that a mail-server commonly communicates with today. For the purpose of this documentation, ESMTP and SMTP are synonymous. Port 465 is the reserved TCP port for Implicit TLS Submission (since 2018). There is actually a boisterous history to that ports usage, but let's keep it simple. Warning This Submission setup is sometimes referred to as SMTPS . Long story short: this is incorrect and should be avoided. Although a very satisfactory setup, Implicit TLS on port 465 is somewhat \"cutting edge\". There exists another well established mail Submission setup that must be supported as well, SMTP+STARTTLS on port 587. It uses Explicit TLS: the client starts with a cleartext connection, then the server informs a TLS-encrypted \"upgraded\" connection may be established, and the client may eventually decide to establish it prior to the Submission. Basically it's an opportunistic, opt-in TLS upgrade of the connection between the client and the server, at the client's discretion, using a mechanism known as STARTTLS that both ends need to implement. In many implementations, the mail-server doesn't enforce TLS encryption, for backwards compatibility. Clients are thus free to deny the TLS-upgrade proposal (or misled by a hacker about STARTTLS not being available), and the server accepts unencrypted (cleartext) mail exchange, which poses a confidentiality threat and, to some extent, spam issues. RFC 8314 (section 3.3) recommends for a mail-server to support both Implicit and Explicit TLS for Submission, and to enforce TLS-encryption on ports 587 (Explicit TLS) and 465 (Implicit TLS). That's exactly docker-mailserver 's default configuration: abiding by RFC 8314, it enforces a strict ( encrypt ) STARTTLS policy , where a denied TLS upgrade terminates the connection thus (hopefully but at the client's discretion) preventing unencrypted (cleartext) Submission. docker-mailserver 's default configuration enables and requires Explicit TLS (STARTTLS) on port 587 for Outward Submission. It does not enable Implicit TLS Outward Submission on port 465 by default. One may enable it through simple custom configuration, either as a replacement or (better!) supplementary mean of secure Submission. It does not support old MUAs (clients) not supporting TLS encryption on ports 587/465 (those should perform Submission on port 25, more details below). One may relax that constraint through advanced custom configuration, for backwards compatibility. A final Outward Submission setup exists and is akin SMTP+STARTTLS on port 587, but on port 25. That port has historically been reserved specifically for unencrypted (cleartext) mail exchange though, making STARTTLS a bit wrong to use. As is expected by RFC 5321 , docker-mailserver uses port 25 for unencrypted Submission in order to support older clients, but most importantly for unencrypted Transfer/Relay between MTAs. docker-mailserver 's default configuration also enables unencrypted (cleartext) on port 25 for Outward Submission. It does not enable Explicit TLS (STARTTLS) on port 25 by default. One may enable it through advanced custom configuration, either as a replacement (bad!) or as a supplementary mean of secure Outward Submission. One may also secure Outward Submission using advanced encryption scheme, such as DANE/DNSSEC and/or MTA-STS.","title":"Outward Submission"},{"location":"introduction/#inward-submission","text":"Granted it's still very difficult enforcing encryption between MTAs (Transfer/Relay) without risking dropping emails (when relayed by MTAs not supporting TLS-encryption), Inward Submission is to be handled in cleartext on port 25 by default. docker-mailserver 's default configuration enables unencrypted (cleartext) on port 25 for Inward Submission.

On the subject of security, one might consider docker-mailserver 's default configuration to not be 100% secure: it enables unencrypted traffic on port 25 it enables Explicit TLS (STARTTLS) on port 587, instead of Implicit TLS on port 465 We believe docker-mailserver 's default configuration to be a good middle ground: it goes slightly beyond \"old\" (1999) RFC 2487 ; and with developer friendly configuration settings, it makes it pretty easy to abide by the \"newest\" (2018) RFC 8314 . Eventually, it is up to you deciding exactly what kind of transportation/encryption to use and/or enforce, and to customize your instance accordingly (with looser or stricter security). Be also aware that protocols and ports on your server can only go so far with security; third-party MTAs might relay your emails on insecure connections, man-in-the-middle attacks might still prove effective, etc. Advanced counter-measure such as DANE, MTA-STS and/or full body encryption (eg.

To get more information, see the detailed documentation page for Rspamd . 0 => disabled 1 => enabled ENABLE_RSPAMD_REDIS Explicit control over running a Redis instance within the container. By default, this value will match what is set for ENABLE_RSPAMD . The purpose of this setting is to opt-out of starting an internal Redis instance when enabling Rspamd, replacing it with your own external instance. Configuring Rspamd for an external Redis instance You will need to provide configuration at /etc/rspamd/local.d/redis.conf similar to: servers = \"redis.example.test:6379\"; expand_keys = true; 0 => Disabled 1 => Enabled RSPAMD_LEARN When enabled, the \" autolearning \" feature is turned on; the Bayes classifier will be trained when moving mails from or to the Junk folder (with the help of Sieve scripts). Attention As of now, the spam learning database is global (i.e. available to all users). If one user deliberately trains it with malicious data, then it will ruin your detection rate. This feature is suitably only for users who can tell ham from spam and users that can be trusted. 0 => Disabled 1 => Enabled Reports PFLOGSUMM_TRIGGER Enables regular Postfix log summary (\"pflogsumm\") mail reports. not set => No report daily_cron => Daily report for the previous day logrotate => Full report based on the mail log when it is rotated This is a new option.

The entire log output for the container is still available via docker logs mailserver (or your respective container name). If you want to configure external log rotation for that container output as well, : Docker Logging Drivers . By default, the logs are lost when the container is destroyed (eg: re-creating via docker-compose down && docker-compose up -d ). To keep the logs, mount a volume (to /var/log/mail/ ). Note This variable can also determine the interval for Postfix's log summary reports, see PFLOGSUMM_TRIGGER . SpamAssassin ENABLE_SPAMASSASSIN 0 => SpamAssassin is disabled 1 => SpamAssassin is enabled SPAMASSASSIN_SPAM_TO_INBOX 0 => Spam messages will be bounced ( rejected ) without any notification ( dangerous ). 1 => Spam messages will be delivered to the inbox and tagged as spam using SA_SPAM_SUBJECT . ENABLE_SPAMASSASSIN_KAM KAM is a 3rd party SpamAssassin ruleset, provided by the McGrail Foundation. If SpamAssassin is enabled, KAM can be used in addition to the default ruleset. 0 => KAM disabled 1 => KAM enabled SA_TAG 2.0 => add spam info headers if at, or above that level Note: this SpamAssassin setting needs ENABLE_SPAMASSASSIN=1 SA_TAG2 6.31 => add 'spam detected' headers at that level Note: this SpamAssassin setting needs ENABLE_SPAMASSASSIN=1 SA_KILL 10.0 => triggers spam evasive actions This SpamAssassin setting needs ENABLE_SPAMASSASSIN=1 By default, docker-mailserver is configured to quarantine spam emails. If emails are quarantined, they are compressed and stored in a location dependent on the ONE_DIR setting above. To inhibit this behaviour and deliver spam emails, set this to a very high value e.g. 100.0 . If ONE_DIR=1 (default) the location is /var/mail-state/lib-amavis/virusmails/ , or if ONE_DIR=0 : /var/lib/amavis/virusmails/ . These paths are inside the docker container. SA_SPAM_SUBJECT ***SPAM*** => add tag to subject if spam detected Note: this SpamAssassin setting needs ENABLE_SPAMASSASSIN=1 . Add the SpamAssassin score to the subject line by inserting the keyword _SCORE_: ***SPAM(_SCORE_)*** . SA_SHORTCIRCUIT_BAYES_SPAM 1 => will activate SpamAssassin short circuiting for bayes spam detection. This will uncomment the respective line in /etc/spamassasin/local.cf Note: activate this only if you are confident in your bayes database for identifying spam. SA_SHORTCIRCUIT_BAYES_HAM 1 => will activate SpamAssassin short circuiting for bayes ham detection This will uncomment the respective line in /etc/spamassasin/local.cf Note: activate this only if you are confident in your bayes database for identifying ham. Fetchmail ENABLE_FETCHMAIL 0 => fetchmail disabled 1 => fetchmail enabled FETCHMAIL_POLL 300 => fetchmail The number of seconds for the interval FETCHMAIL_PARALLEL 0 => fetchmail runs with a single config file /etc/fetchmailrc 1 => /etc/fetchmailrc is split per poll entry. For every poll entry a separate fetchmail instance is started to allow having multiple imap idle configurations defined. Note: The defaults of your fetchmailrc file need to be at the top of the file. Otherwise it won't be added correctly to all separate fetchmail instances. LDAP ENABLE_LDAP Deprecated. See ACCOUNT_PROVISIONER .

LDAP_QUERY_FILTER_* Those variables contain the LDAP lookup filters for postfix, using %s as the placeholder for the domain or email address in question. This means that... ...for incoming email, the domain must return an entry for the DOMAIN filter (see virtual_alias_domains ). ...for incoming email, the inboxes which receive the email are chosen by the USER , ALIAS and GROUP filters. The USER filter specifies personal mailboxes, for which only one should exist per address, for example (mail=%s) (also see virtual_mailbox_maps ) The ALIAS filter specifies aliases for mailboxes, using virtual_alias_maps , for example (mailAlias=%s) The GROUP filter specifies the personal mailboxes in a group (for emails that multiple people shall receive), using virtual_alias_maps , for example (mailGroupMember=%s) . Technically, there is no difference between ALIAS and GROUP , but ideally you should use ALIAS for personal aliases for a singular person (like ceo@example.org ) and GROUP for multiple people (like hr@example.org ). ...for outgoing email, the sender address is put through the SENDERS filter, and only if the authenticated user is one of the returned entries, the email can be sent. This only applies if SPOOF_PROTECTION=1 . If the SENDERS filter is missing, the USER , ALIAS and GROUP filters will be used in in a disjunction (OR). To for example allow users from the admin group to spoof any sender email address, and to force everyone else to only use their personal mailbox address for outgoing email, you can use something like this: (|(memberOf=cn=admin,*)(mail=%s)) Example A really simple LDAP_QUERY_FILTER configuration, using only the user filter and allowing only admin@* to spoof any sender addresses. - ENABLE_LDAP=1 # with the :edge tag, use ACCOUNT_PROVISIONER - LDAP_START_TLS=yes - ACCOUNT_PROVISIONER=LDAP - LDAP_SERVER_HOST=ldap.example.org - LDAP_SEARCH_BASE=dc=example,dc=org\" - LDAP_BIND_DN=cn=admin,dc=example,dc=org - LDAP_BIND_PW=mypassword - SPOOF_PROTECTION=1 - LDAP_QUERY_FILTER_DOMAIN=(mail=*@%s) - LDAP_QUERY_FILTER_USER=(mail=%s) - LDAP_QUERY_FILTER_ALIAS=(|) # doesn't match anything - LDAP_QUERY_FILTER_GROUP=(|) # doesn't match anything - LDAP_QUERY_FILTER_SENDERS=(|(mail=%s)(mail=admin@*)) DOVECOT_*_FILTER & DOVECOT_*_ATTRS These variables specify the LDAP filters that dovecot uses to determine if a user can log in to their IMAP account, and which mailbox is responsible to receive email for a specific postfix user. This is split into the following two lookups, both using %u as the placeholder for the full login name ( see dovecot documentation for a full list of placeholders ). Usually you only need to set DOVECOT_USER_FILTER , in which case it will be used for both filters. DOVECOT_USER_FILTER is used to get the account details (uid, gid, home directory, quota, ...) of a user. DOVECOT_PASS_FILTER is used to get the password information of the user, and is in pretty much all cases identical to DOVECOT_USER_FILTER (which is the default behaviour if left away). If your directory doesn't have the postfix-book schema installed, then you must change the internal attribute handling for dovecot. For this you have to change the pass_attr and the user_attr mapping, as shown in the example below: - DOVECOT_PASS_ATTRS=<YOUR_USER_IDENTIFIER_ATTRIBUTE>=user,<YOUR_USER_PASSWORD_ATTRIBUTE>=password - DOVECOT_USER_ATTRS=<YOUR_USER_HOME_DIRECTORY_ATTRIBUTE>=home,<YOUR_USER_MAILSTORE_ATTRIBUTE>=mail,<YOUR_USER_MAIL_UID_ATTRIBUTE>=uid,<YOUR_USER_MAIL_GID_ATTRIBUTE>=gid Note For DOVECOT_*_ATTRS , you can replace ldapAttr=dovecotAttr with =dovecotAttr=%{ldap:ldapAttr} for more flexibility, like for example =home=/var/mail/%{ldap:uid} or just =uid=5000 . A list of dovecot attributes can be found in the dovecot documentation . Defaults - DOVECOT_USER_ATTRS=mailHomeDirectory=home,mailUidNumber=uid,mailGidNumber=gid,mailStorageDirectory=mail - DOVECOT_PASS_ATTRS=uniqueIdentifier=user,userPassword=password - DOVECOT_USER_FILTER=(&(objectClass=PostfixBookMailAccount)(uniqueIdentifier=%n)) Example Setup for a directory that has the qmail-schema installed and uses uid : - DOVECOT_PASS_ATTRS=uid=user,userPassword=password - DOVECOT_USER_ATTRS=homeDirectory=home,qmailUID=uid,qmailGID=gid,mailMessageStore=mail - DOVECOT_USER_FILTER=(&(objectClass=qmailUser)(uid=%u)(accountStatus=active)) The LDAP server configuration for dovecot will be taken mostly from postfix, other options can be found in the environment section in the docs . DOVECOT_AUTH_BIND Set this to yes to enable authentication binds ( more details in the dovecot documentation ). Currently, only DN lookup is supported without further changes to the configuration files, so this is only useful when you want to bind as a readonly user without the permission to read passwords. SASLAUTHD_LDAP_FILTER This filter is used for saslauthd , which is called by postfix when someone is authenticating through SMTP (assuming that SASLAUTHD_MECHANISMS=ldap is being used). Note that you'll need to set up the LDAP server for saslauthd separately from postfix. The filter variables are explained in detail in the LDAP_SASLAUTHD file , but unfortunately, this method doesn't really support domains right now - that means that %U is the only token that makes sense in this variable. When to use this and how to avoid it Using a separate filter for SMTP authentication allows you to for example allow noreply@example.org to send email, but not log in to IMAP or receive email: (&(mail=%U@example.org)(|(memberOf=cn=email,*)(mail=noreply@example.org))) If you don't want to use a separate filter for SMTP authentication, you can set SASLAUTHD_MECHANISMS=rimap and SASLAUTHD_MECH_OPTIONS=127.0.0.1 to authenticate against dovecot instead - this means that the DOVECOT_USER_FILTER and DOVECOT_PASS_FILTER will be used for SMTP authentication as well. Configure LDAP with saslauthd - ENABLE_SASLAUTHD=1 - SASLAUTHD_MECHANISMS=ldap - SASLAUTHD_LDAP_FILTER=(mail=%U@example.org) Secure Connection with LDAPS or StartTLS To enable LDAPS, all you need to do is to add the protocol to LDAP_SERVER_HOST , for example ldaps://example.org:636 . To enable LDAP over StartTLS (on port 389), you need to set the following environment variables instead (the protocol must not be ldaps:// in this case!): - LDAP_START_TLS=yes - DOVECOT_TLS=yes - SASLAUTHD_LDAP_START_TLS=yes Active Directory Configurations (Tested with Samba4 AD Implementation) In addition to LDAP explanation above, when Docker Mailserver is intended to be used with Active Directory (or the equivalent implementations like Samba4 AD DC) the following points should be taken into consideration: Samba4 Active Directory requires a secure connection to the domain controller (DC), either via SSL/TLS (LDAPS) or via StartTLS. The username equivalent in Active Directory is: sAMAccountName . proxyAddresses can be used to store email aliases of single users. The convention is to prefix the email aliases with smtp: (e.g: smtp:some.name@example.com ). Active Directory is used typically not only as LDAP Directory storage, but also as a domain controller , i.e., it will do many things including authenticating users. Mixing Linux and Windows clients requires the usage of RFC2307 attributes , namely uidNumber , gidNumber instead of the typical uid . Assigning different owner to email folders can also be done in this approach, nevertheless there is a bug at the moment in Docker Mailserver that overwrites all permissions when starting the container. Either a manual fix is necessary now, or a temporary workaround to use a hard-coded ldap:uidNumber that equals to 5000 until this issue is fixed. To deliver the emails to different members of Active Directory Security Group or Distribution Group (similar to mailing lists), use a user-patches.sh script to modify ldap-groups.cf so that it includes leaf_result_attribute = mail and special_result_attribute = member . This can be achieved simply by: The configuration shown to get the Group to work is from here and here . # user-patches.sh ... grep -q '^leaf_result_attribute = mail$' /etc/postfix/ldap-groups.cf || echo \"leaf_result_attribute = mail\" >> /etc/postfix/ldap-groups.cf grep -q '^special_result_attribute = member$' /etc/postfix/ldap-groups.cf || echo \"special_result_attribute = member\" >> /etc/postfix/ldap-groups.cf ... In /etc/ldap/ldap.conf , if the TLS_REQCERT is demand / hard (default), the CA certificate used to verify the LDAP server certificate must be recognized as a trusted CA. This can be done by volume mounting the ca.crt file and updating the trust store via a user-patches.sh script: # user-patches.sh ... cp /MOUNTED_FOLDER/ca.crt /usr/local/share/ca-certificates/ update-ca-certificates ... The changes on the configurations necessary to work with Active Directory ( only changes are listed, the rest of the LDAP configuration can be taken from the other examples shown in this documentation): # If StartTLS is the chosen method to establish a secure connection with Active Directory. - LDAP_START_TLS=yes - SASLAUTHD_LDAP_START_TLS=yes - DOVECOT_TLS=yes - LDAP_QUERY_FILTER_USER=(&(objectclass=person)(mail=%s)) - LDAP_QUERY_FILTER_ALIAS=(&(objectclass=person)(proxyAddresses=smtp:%s)) # Filters Active Directory groups (mail lists).

Dovecot supports a variety of community supported FTS indexing backends . docker-mailserver comes pre-installed with two plugins that can be enabled with a dovecot config file. Please be aware that indexing consumes memory and takes up additional disk space. Xapian The dovecot-fts-xapian plugin makes use of Xapian . Xapian enables embedding an FTS engine without the need for additional backends. The indexes will be stored as a subfolder named xapian-indexes inside your local mail-data folder ( /var/mail internally ). With the default settings, 10GB of email data may generate around 4GB of indexed data.

Especially the issue will need to be configured. Since we do not know how you want or need your certificates to be supplied, we do not provide more configuration here. The documentation for cert-manager is excellent. Sensitive Data Sensitive Data For storing OpenDKIM keys, TLS certificates or any sort of sensitive data, you should be using Secret s. You can mount secrets like ConfigMap s and use them the same way. The TLS docs page provides guidance when it comes to certificates and transport layer security. Always provide sensitive information vai Secrets . Exposing your Mail-Server to the Outside World The more difficult part with Kubernetes is to expose a deployed docker-mailserver to the outside world. Kubernetes provides multiple ways for doing that; each has downsides and complexity. The major problem with exposing docker-mailserver to outside world in Kubernetes is to preserve the real client IP . The real client IP is required by docker-mailserver for performing IP-based SPF checks and spam checks. If you do not require SPF checks for incoming mails, you may disable them in your Postfix configuration by dropping the line that states: check_policy_service unix:private/policyd-spf . The easiest approach was covered above, using externalTrafficPolicy : Local , which disables the service proxy, but makes the service local as well (which does not scale). This approach only works when you are given the correct (that is, a public and routable) IP address by a load balancer (like MetalLB). In this sense, the approach above is similar to the next example below. We want to provide you with a few alternatives too. But we also want to communicate the idea of another simple method: you could use a load-balancer without an external IP and DNAT the network traffic to the mail-server. After all, this does not interfere with SPF checks because it keeps the origin IP address. If no dedicated external IP address is available, you could try the latter approach, if one is available, use the former. External IPs Service The simplest way is to expose docker-mailserver as a Service with external IPs . This is very similar to the approach taken above. Here, an external IP is given to the service directly by you. With the approach above, you tell your load-balancer to do this. --- apiVersion : v1 kind : Service metadata : name : mailserver labels : app : mailserver spec : selector : app : mailserver ports : - name : smtp port : 25 targetPort : smtp # ... externalIPs : - 80.11.12.10 This approach does not preserve the real client IP, so SPF check of incoming mail will fail. requires you to specify the exposed IPs explicitly. Proxy port to Service The proxy pod helps to avoid the necessity of specifying external IPs explicitly. This comes at the cost of complexity; you must deploy a proxy pod on each Node you want to expose docker-mailserver on. This approach does not preserve the real client IP, so SPF check of incoming mail will fail. Bind to concrete Node and use host network One way to preserve the real client IP is to use hostPort and hostNetwork: true . This comes at the cost of availability; you can reach docker-mailserver from the outside world only via IPs of Node where docker-mailserver is deployed. --- apiVersion : extensions/v1beta1 kind : Deployment metadata : name : mailserver # ... spec : hostNetwork : true # ... containers : # ... ports : - name : smtp containerPort : 25 hostPort : 25 - name : smtp-auth containerPort : 587 hostPort : 587 - name : imap-secure containerPort : 993 hostPort : 993 # ... With this approach, it is not possible to access docker-mailserver via other cluster Nodes, only via the Node docker-mailserver was deployed at. every Port within the Container is exposed on the Host side. Proxy Port to Service via PROXY Protocol This way is ideologically the same as using a proxy pod , but instead of a separate proxy pod, you configure your ingress to proxy TCP traffic to the docker-mailserver pod using the PROXY protocol, which preserves the real client IP. Configure your Ingress With an NGINX ingress controller , set externalTrafficPolicy: Local for its service, and add the following to the TCP services config map (as described here ): 25 : \"mailserver/mailserver:25::PROXY\" 465 : \"mailserver/mailserver:465::PROXY\" 587 : \"mailserver/mailserver:587::PROXY\" 993 : \"mailserver/mailserver:993::PROXY\" HAProxy With HAProxy , the configuration should look similar to the above. If you know what it actually looks like, add an example here. Configure the Mailserver Then, configure both Postfix and Dovecot to expect the PROXY protocol: HAProxy Example kind : ConfigMap apiVersion : v1 metadata : name : mailserver.config labels : app : mailserver data : postfix-main.cf : | postscreen_upstream_proxy_protocol = haproxy postfix-master.cf : | smtp/inet/postscreen_upstream_proxy_protocol=haproxy submission/inet/smtpd_upstream_proxy_protocol=haproxy smtps/inet/smtpd_upstream_proxy_protocol=haproxy dovecot.cf : | # Assuming your ingress controller is bound to 10.0.0.0/8 haproxy_trusted_networks = 10.0.0.0/8, 127.0.0.0/8 service imap-login { inet_listener imap { haproxy = yes } inet_listener imaps { haproxy = yes } } # ... --- kind : Deployment apiVersion : extensions/v1beta1 metadata : name : mailserver spec : template : spec : containers : - name : docker-mailserver volumeMounts : - name : config subPath : postfix-main.cf mountPath : /tmp/docker-mailserver/postfix-main.cf readOnly : true - name : config subPath : postfix-master.cf mountPath : /tmp/docker-mailserver/postfix-master.cf readOnly : true - name : config subPath : dovecot.cf mountPath : /tmp/docker-mailserver/dovecot.cf readOnly : true With this approach, it is not possible to access docker-mailserver via cluster-DNS, as the PROXY protocol is required for incoming connections.","title":"Kubernetes"},{"location":"config/advanced/kubernetes/#introduction","text":"This article describes how to deploy docker-mailserver to Kubernetes.

Kubernetes provides multiple ways for doing that; each has downsides and complexity. The major problem with exposing docker-mailserver to outside world in Kubernetes is to preserve the real client IP . The real client IP is required by docker-mailserver for performing IP-based SPF checks and spam checks. If you do not require SPF checks for incoming mails, you may disable them in your Postfix configuration by dropping the line that states: check_policy_service unix:private/policyd-spf . The easiest approach was covered above, using externalTrafficPolicy : Local , which disables the service proxy, but makes the service local as well (which does not scale). This approach only works when you are given the correct (that is, a public and routable) IP address by a load balancer (like MetalLB). In this sense, the approach above is similar to the next example below. We want to provide you with a few alternatives too. But we also want to communicate the idea of another simple method: you could use a load-balancer without an external IP and DNAT the network traffic to the mail-server. After all, this does not interfere with SPF checks because it keeps the origin IP address. If no dedicated external IP address is available, you could try the latter approach, if one is available, use the former.","title":"Exposing your Mail-Server to the Outside World"},{"location":"config/advanced/kubernetes/#external-ips-service","text":"The simplest way is to expose docker-mailserver as a Service with external IPs .

About Support for Podman Please note that Podman is not officially supported as docker-mailserver is built and verified on top of the Docker Engine . This content is entirely community supported. If you find errors, please open an issue and provide a PR. About this Guide This guide was tested with Fedora 34 using systemd and firewalld . Moreover, it requires Podman version >= 3.2. You may be able to substitute dnf - Fedora's package manager - with others such as apt . About Security Running podman in rootless mode requires additional modifications in order to keep your mailserver secure. Make sure to read the related documentation. Installation in Rootfull Mode While using Podman, you can just manage docker-mailserver as what you did with Docker. Your best friend setup.sh includes the minimum code in order to support Podman since it's 100% compatible with the Docker CLI. The installation is basically the same. Podman v3.2 introduced a RESTful API that is 100% compatible with the Docker API, so you can use docker-compose with Podman easily. Install Podman and docker-compose with your package manager first. sudo dnf install podman docker-compose Then enable podman.socket using systemctl . systemctl enable --now podman.socket This will create a unix socket locate under /run/podman/podman.sock , which is the entrypoint of Podman's API. Now, configure docker-mailserver and start it. export DOCKER_HOST = \"unix:///run/podman/podman.sock\" docker-compose up -d mailserver docker-compose ps You should see that docker-mailserver is running now. Self-start in Rootfull Mode Podman is daemonless, that means if you want docker-mailserver self-start while boot up the system, you have to generate a systemd file with Podman CLI. podman generate systemd mailserver > /etc/systemd/system/mailserver.service systemctl daemon-reload systemctl enable --now mailserver.service Installation in Rootless Mode Running rootless containers is one of Podman's major features. But due to some restrictions, deploying docker-mailserver in rootless mode is not as easy compared to rootfull mode. a rootless container is running in a user namespace so you cannot bind ports lower than 1024 a rootless container's systemd file can only be placed in folder under ~/.config a rootless container can result in an open relay, make sure to read the security section . Also notice that Podman's rootless mode is not about running as a non-root user inside the container, but about the mapping of (normal, non-root) host users to root inside the container. Warning In order to make rootless docker-mailserver work we must modify some settings in the Linux system, it requires some basic linux server knowledge so don't follow this guide if you not sure what this guide is talking about. Podman rootfull mode and Docker are still good and security enough for normal daily usage. First, enable podman.socket in systemd's userspace with a non-root user. systemctl enable --now --user podman.socket The socket file should be located at /var/run/user/$(id -u)/podman/podman.sock . Then, modify docker-compose.yml to make sure all ports are bindings are on non-privileged ports. services : mailserver : ports : - \"10025:25\" # SMTP (explicit TLS => STARTTLS) - \"10143:143\" # IMAP4 (explicit TLS => STARTTLS) - \"10465:465\" # ESMTP (implicit TLS) - \"10587:587\" # ESMTP (explicit TLS => STARTTLS) - \"10993:993\" # IMAP4 (implicit TLS) Then, setup your mailserver.env file follow the documentation and use docker-compose to start the container. export DOCKER_HOST = \"unix:///var/run/user/ $( id -u ) /podman/podman.sock\" docker-compose up -d mailserver docker-compose ps Security in Rootless Mode In rootless mode, podman resolves all incoming IPs as localhost, which results in an open gateway in the default configuration. There are two workarounds to fix this problem, both of which have their own drawbacks. Enforce authentication from localhost The PERMIT_DOCKER variable in the mailserver.env file allows to specify trusted networks that do not need to authenticate. If the variable is left empty, only requests from localhost and the container IP are allowed, but in the case of rootless podman any IP will be resolved as localhost. Setting PERMIT_DOCKER=none enforces authentication also from localhost, which prevents sending unauthenticated emails. Use the slip4netns network driver The second workaround is slightly more complicated because the docker-compose.yml has to be modified. As shown in the fail2ban section the slirp4netns network driver has to be enabled. This network driver enables podman to correctly resolve IP addresses but it is not compatible with user defined networks which might be a problem depending on your setup. Rootless Podman requires adding the value slirp4netns:port_handler=slirp4netns to the --network CLI option, or network_mode setting in your docker-compose.yml . You must also add the ENV NETWORK_INTERFACE=tap0 , because Podman uses a hard-coded interface name for slirp4netns . Example services : mailserver : network_mode : \"slirp4netns:port_handler=slirp4netns\" environment : - NETWORK_INTERFACE=tap0 ... Note podman-compose is not compatible with this configuration. Self-start in Rootless Mode Generate a systemd file with the Podman CLI. podman generate systemd mailserver > ~/.config/systemd/user/mailserver.service systemctl --user daemon-reload systemctl enable --user --now mailserver.service Systemd's user space service is only started when a specific user logs in and stops when you log out. In order to make it to start with the system, we need to enable linger with loginctl loginctl enable-linger <username> Remember to run this command as root user.

You will need to create some Amazon SES SMTP credentials . The SMTP credentials you create will be used to populate the RELAY_USER and RELAY_PASSWORD environment variables. The RELAY_HOST should match your AWS SES region , the RELAY_PORT will be 587. If all of your email is being forwarded through AWS SES, DEFAULT_RELAY_HOST should be set accordingly.

The list of authorized sending hosts for a domain is published in the Domain Name System (DNS) records for that domain in the form of a specially formatted TXT record. Email spam and phishing often use forged \"from\" addresses, so publishing and checking SPF records can be considered anti-spam techniques. Note For a more technical review: https://github.com/internetstandards/toolbox-wiki/blob/master/SPF-how-to.md Add a SPF Record To add a SPF record in your DNS, insert the following line in your DNS zone: ; MX record must be declared for SPF to work example.com. IN MX 1 mail.example.com. ; SPF record example.com. IN TXT \"v=spf1 mx ~all\" This enables the Softfail mode for SPF. You could first add this SPF record with a very low TTL. SoftFail is a good setting for getting started and testing, as it lets all email through, with spams tagged as such in the mailbox. After verification, you might want to change your SPF record to v=spf1 mx -all so as to enforce the HardFail policy. See http://www.open-spf.org/SPF_Record_Syntax for more details about SPF policies. In any case, increment the SPF record's TTL to its final value. Backup MX, Secondary MX For whitelisting an IP Address from the SPF test, you can create a config file (see policyd-spf.conf ) and mount that file into /etc/postfix-policyd-spf-python/policyd-spf.conf .

We are confident that there are no major bugs in our integration that make using Rspamd infeasible. Please note that there may still be (breaking) changes ahead as integration is still work in progress! We expect to stabilize this feature with version v12.1.0 . About Rspamd is a \"fast, free and open-source spam filtering system\" . DMS integrates Rspamd like any other service. We provide a very simple but easy to maintain setup of Rspamd. If you want to have a look at the default configuration files for Rspamd that DMS packs, navigate to target/rspamd/ inside the repository . Please consult the section \"The Default Configuration\" section down below for a written overview. AMD64 vs ARM64 We are currently doing a best-effort installation of Rspamd for ARM64 (from the Debian backports repository for Debian 11). The current version difference is two minor versions (AMD64 is at version 3.4, ARM64 at 3.2 [13th Feb 2023]). Maintainers noticed only few differences, some of them with a big impact though. For those running Rspamd on ARM64, we recommend disabling the DKIM signing module if you don't use it. The following environment variables are related to Rspamd: ENABLE_RSPAMD ENABLE_RSPAMD_REDIS RSPAMD_LEARN MOVE_SPAM_TO_JUNK The Default Configuration Mode of Operation The proxy worker operates in self-scan mode . This simplifies the setup as we do not require a normal worker. You can easily change this though by overriding the configuration by DMS . DMS does not set a default password for the controller worker. You may want to do that yourself. In setups where you already have an authentication provider in front of the Rspamd webpage, you may want to set the secure_ip option to \"0.0.0.0/0\" for the controller worker to disable password authentication inside Rspamd completely. Persistence with Redis When Rspamd is enabled, we implicitly also start an instance of Redis in the container. Redis is configured to persist it's data via RDB snapshots to disk in the directory /var/lib/redis ( which is a symbolic link to /var/mail-state/lib-redis/ when ONE_DIR=1 and a volume is mounted to /var/mail-state/ ). With the volume mount the snapshot will restore the Redis data across container restarts, and provide a way to keep backup. Redis uses /etc/redis/redis.conf for configuration. We adjust this file when enabling the internal Redis service. If you have an external instance of Redis to use, the internal Redis service can be opt-out via setting the ENV ENABLE_RSPAMD_REDIS=0 ( link also details required changes to the DMS rspamd config ). Modules You can find a list of all Rspamd modules on their website . Disabled By Default DMS disables certain modules (clickhouse, elastic, greylist, neural, reputation, spamassassin, url_redirector, metric_exporter) by default. We believe these are not required in a standard setup, and they would otherwise needlessly use system resources. Anti-Virus (ClamAV) You can choose to enable ClamAV, and Rspamd will then use it to check for viruses. Just set the environment variable ENABLE_CLAMAV=1 . RBLs (Realtime Blacklists) / DNSBLs (DNS-based Blacklists) The RBL module is enabled by default. As a consequence, Rspamd will perform DNS lookups to a variety of blacklists. Whether an RBL or a DNSBL is queried depends on where the domain name was obtained: RBL servers are queried with IP addresses extracted from message headers, DNSBL server are queried with domains and IP addresses extracted from the message body [ source ]. Rspamd and DNS Block Lists When the RBL module is enabled, Rspamd will do a variety of DNS requests to (amongst other things) DNSBLs. There are a variety of issues involved when using DNSBLs. Rspamd will try to mitigate some of them by properly evaluating all return codes. This evaluation is a best effort though, so if the DNSBL operators change or add return codes, it may take a while for Rspamd to adjust as well. If you want to use DNSBLs, try to use your own DNS resolver and make sure it is set up correctly, i.e. it should be a non-public & recursive resolver. Otherwise, you might not be able ( see this Spamhaus post ) to make use of the block lists. Providing Custom Settings & Overriding Settings Manually DMS brings sane default settings for Rspamd. They are located at /etc/rspamd/local.d/ inside the container (or target/rspamd/local.d/ in the repository). If you want to change these settings and / or provide your own settings, you can place files at /etc/rspamd/override.d/ which will override Rspamd settings and DMS settings (re-)place files at /etc/rspamd/local.d/ to override DMS settings and merge them with Rspamd settings Clashing Overrides Note that when also using the rspamd-commands file , files in override.d may be overwritten in case you adjust them manually and with the help of the file. With the Help of a Custom File DMS provides the ability to do simple adjustments to Rspamd modules with the help of a single file. Just place a file called rspamd-modules.conf into the directory docker-data/dms/config/ (which translates to /tmp/docker-mailserver/ in the container). If this file is present, DMS will evaluate it. The structure is very simple. Each line in the file looks like this: COMMAND ARGUMENT1 ARGUMENT2 ARGUMENT3 where COMMAND can be: disable-module : disables the module with name ARGUMENT1 enable-module : explicitly enables the module with name ARGUMENT1 set-option-for-module : sets the value for option ARGUMENT2 to ARGUMENT3 inside module ARGUMENT1 set-option-for-controller : set the value of option ARGUMENT1 to ARGUMENT2 for the controller worker set-option-for-proxy : set the value of option ARGUMENT1 to ARGUMENT2 for the proxy worker set-common-option : set the option ARGUMENT1 that defines basic Rspamd behaviour to value ARGUMENT2 add-line : this will add the complete line after ARGUMENT1 (with all characters) to the file /etc/rspamd/override.d/<ARGUMENT1> An Example Is Shown Down Below File Names & Extensions For command 1 - 3, we append the .conf suffix to the module name to get the correct file name automatically. For commands 4 - 6, the file name is fixed (you don't even need to provide it). For command 7, you will need to provide the whole file name (including the suffix) yourself! You can also have comments (the line starts with # ) and blank lines in rspamd-modules.conf - they are properly handled and not evaluated. Adjusting Modules This Way These simple commands are meant to give users the ability to easily alter modules and their options. As a consequence, they are not powerful enough to enable multi-line adjustments. If you need to do something more complex, we advise to do that manually ! Examples & Advanced Configuration A Very Basic Configuration You want to start using Rspamd? Rspamd is disabled by default, so you need to set the following environment variables: ENABLE_RSPAMD = 1 ENABLE_OPENDKIM = 0 ENABLE_OPENDMARC = 0 ENABLE_AMAVIS = 0 ENABLE_SPAMASSASSIN = 0 This will enable Rspamd and disable services you don't need when using Rspamd. Note that with this setup, the default DKIM signing that DMS provides does not work (as it is disabled)! To solve this issue, look at this subsection . Adjusting and Extending The Very Basic Configuration Rspamd is running, but you want or need to adjust it? Say you want to be able to easily look at the frontend Rspamd provides on port 11334 (default) without the need to enter a password (maybe because you already provide authorization and authentication). You will need to adjust the controller worker: create a file called rspamd-modules.conf and add the line set-option-for-controller secure_ip \"0.0.0.0/0\" . Place the file rspamd-modules.conf inside the directory on the host you mount to /tmp/docker-mailserver/ inside the container (in our documentation, we use docker-data/dms/config on the host for this purpose). And you're done! Note: this disables authentication on the website - make sure you know what you're doing! You additionally want to enable the auto-spam-learning for the Bayes module? No problem, just add another line to rspamd-modules.conf that looks like this: set-option-for-module classifier-bayes autolearn true . But the chartable module gets on your nerves? Just disable it by adding another line: disable-module chartable . DKIM Signing By default, DMS offers no option to generate and configure signing e-mails with DKIM. This is because the parsing would be difficult. But don't worry: the process is relatively straightforward nevertheless. The official Rspamd documentation for the DKIM signing module is pretty good. Basically, you need to exec into the container Run a command similar to rspamadm dkim_keygen -s 'woosh' -b 2048 -d example.com -k example.private > example.txt , adjusted to your needs Make sure to then persists the files example.private and example.txt (created in step 2) in the container (for example with a Docker bind mount) Create a configuration for the DKIM signing module, i.e. a file called dkim_signing.conf that you mount to /etc/rspamd/local.d/ or /etc/rspamd/override.d/ . We provide example configurations down below. We recommend mounting this file into the container as well (as described here ); do not use rspamd-modules.conf for this purpose. DKIM Signing Module Configuration Examples A simple configuration could look like this: # documentation: https://rspamd.com/doc/modules/dkim_signing.html enabled = true; sign_authenticated = true; sign_local = true; use_domain = \"header\"; use_redis = false; # don't change unless Redis also provides the DKIM keys use_esld = true; check_pubkey = true; domain { example.com { path = \"/path/to/example.private\"; selector = \"woosh\"; } } If you have multiple domains and you want to sign with the modern ED25519 elliptic curve but also with RSA (you will likely want to have RSA as a fallback!): # documentation: https://rspamd.com/doc/modules/dkim_signing.html enabled = true; sign_authenticated = true; sign_local = true; use_domain = \"header\"; use_redis = false; # don't change unless Redis also provides the DKIM keys use_esld = true; check_pubkey = true; domain { example.com { selectors [ { path = \"/path/to/com.example.rsa.private\"; selector = \"dkim-rsa\"; }, { path = /path/to/com.example.ed25519.private\"; selector = \"dkim-ed25519\"; } ] } example.org { selectors [ { path = \"/path/to/org.example.rsa.private\"; selector = \"dkim-rsa\"; }, { path = \"/path/to/org.example.ed25519.private\"; selector = \"dkim-ed25519\"; } ] } } Abusix Integration This subsection gives information about the integration of Abusix , \"a set of blocklists that work as an additional email security layer for your existing mail environment\". The setup is straight-forward and well documented: Create an account Retrieve your API key Navigate to the \"Getting Started\" documentation for Rspamd and follow the steps described there Make sure to change <APIKEY> to your private API key We recommend mounting the files directly into the container, as they are rather big and not manageable with the modules script . If mounted to the correct location, Rspamd will automatically pick them up. While Abusix can be integrated into Postfix, Postscreen and a multitude of other software, we recommend integrating Abusix only into a single piece of software running in your mail server - everything else would be excessive and wasting queries. Moreover, we recommend the integration into suitable filtering software and not Postfix itself, as software like Postscreen or Rspamd can properly evaluate the return codes and other configuration.","title":"Rspamd"},{"location":"config/security/rspamd/#about","text":"Rspamd is a \"fast, free and open-source spam filtering system\" .

Example Add these additions to the mailserver service in your docker-compose.yml : services : mailserver : # For the FQDN 'mail.example.com': hostname : mail domainname : example.com environment : - SSL_TYPE=letsencrypt volumes : - /etc/letsencrypt:/etc/letsencrypt Example using Docker for Let's Encrypt Certbot provisions certificates to /etc/letsencrypt . Add a volume to store these, so that they can later be accessed by docker-mailserver container. You may also want to persist Certbot logs , just in case you need to troubleshoot. Getting a certificate is this simple! ( Referencing: Certbot docker instructions and certonly --standalone mode ): # Change `mail.example.com` below to your own FQDN. # Requires access to port 80 from the internet, adjust your firewall if needed. docker run --rm -it \\ -v \" ${ PWD } /docker-data/certbot/certs/:/etc/letsencrypt/\" \\ -v \" ${ PWD } /docker-data/certbot/logs/:/var/log/letsencrypt/\" \\ -p 80 :80 \\ certbot/certbot certonly --standalone -d mail.example.com Add a volume for docker-mailserver that maps the local certbot/certs/ folder to the container path /etc/letsencrypt/ . Example Add these additions to the mailserver service in your docker-compose.yml : services : mailserver : # For the FQDN 'mail.example.com': hostname : mail domainname : example.com environment : - SSL_TYPE=letsencrypt volumes : - ./docker-data/certbot/certs/:/etc/letsencrypt The certificate setup is complete, but remember it will expire . Consider automating renewals. Renewing Certificates When running the above certonly --standalone snippet again, the existing certificate is renewed if it would expire within 30 days. Alternatively, Certbot can look at all the certificates it manages, and only renew those nearing their expiry via the renew command : # This will need access to port 443 from the internet, adjust your firewall if needed. docker run --rm -it \\ -v \" ${ PWD } /docker-data/certbot/certs/:/etc/letsencrypt/\" \\ -v \" ${ PWD } /docker-data/certbot/logs/:/var/log/letsencrypt/\" \\ -p 80 :80 \\ -p 443 :443 \\ certbot/certbot renew This process can also be automated via cron or systemd timers . Using a different ACME CA Certbot does support alternative certificate providers via the --server option. In most cases you'll want to use the default Let's Encrypt . Example using certbot-dns-cloudflare with Docker If you are unable get a certificate via the HTTP-01 (port 80) or TLS-ALPN-01 (port 443) challenge types , the DNS-01 challenge can be useful ( this challenge can additionally issue wildcard certificates ). This guide shows how to use the DNS-01 challenge with Cloudflare as your DNS provider. Obtain a Cloudflare API token: Login into your Cloudflare dashboard. Navigate to the API Tokens page . Click \"Create Token\", and choose the Edit zone DNS template ( Certbot requires the ZONE:DNS:Edit permission ). Only include the necessary Zone resource configuration Be sure to configure \"Zone Resources\" section on this page to Include -> Specific zone -> <your zone here> . This restricts the API token to only this zone (domain) which is an important security measure. Store the API token you received in a file cloudflare.ini with content: dns_cloudflare_api_token = YOUR_CLOUDFLARE_TOKEN_HERE As this is sensitive data, you should restrict access to it with chmod 600 and chown 0:0 . Store the file in a folder if you like, such as docker-data/certbot/secrets/ . Your docker-compose.yml should include the following: services : mailserver : environments : # Set SSL certificate type. - SSL_TYPE=letsencrypt volumes : # Mount the cert folder generated by Certbot into mail-server: - ./docker-data/certbot/certs/:/etc/letsencrypt/:ro certbot-cloudflare : image : certbot/dns-cloudflare:latest command : certonly --dns-cloudflare --dns-cloudflare-credentials /run/secrets/cloudflare-api-token -d mail.example.com volumes : - ./docker-data/certbot/certs/:/etc/letsencrypt/ - ./docker-data/certbot/logs/:/var/log/letsencrypt/ secrets : - cloudflare-api-token # Docs: https://docs.docker.com/engine/swarm/secrets/#use-secrets-in-compose # WARNING: In compose configs without swarm, the long syntax options have no effect, # Ensure that you properly `chmod 600` and `chown 0:0` the file on disk. Effectively treated as a bind mount. secrets : cloudflare-api-token : file : ./docker-data/certbot/secrets/cloudflare.ini Alternative using the docker run command ( secrets feature is not available): docker run \\ --volume \" ${ PWD } /docker-data/certbot/certs/:/etc/letsencrypt/\" \\ --volume \" ${ PWD } /docker-data/certbot/logs/:/var/log/letsencrypt/\" \\ --volume \" ${ PWD } /docker-data/certbot/secrets/:/tmp/secrets/certbot/\" certbot/dns-cloudflare \\ certonly --dns-cloudflare --dns-cloudflare-credentials /tmp/secrets/certbot/cloudflare.ini -d mail.example.com Run the service to provision a certificate: docker-compose run certbot-cloudflare You should see the following log output: Saving debug log to /var/log/letsencrypt/letsencrypt. log | Requesting a certificate for mail.example.com Waiting 10 seconds for DNS changes to propagate Successfully received certificate. Certificate is saved at: /etc/letsencrypt/live/mail.example.com/fullchain.pem Key is saved at: /etc/letsencrypt/live/mail.example.com/privkey.pem This certificate expires on YYYY-MM-DD. These files will be updated when the certificate renews. NEXT STEPS: - The certificate will need to be renewed before it expires. Certbot can automatically renew the certificate in background, but you may need to take steps to enable that functionality. See https://certbot.org/renewal structions. After completing the steps above, your certificate should be ready to use. Renewing a certificate (Optional) We've only demonstrated how to provision a certificate, but it will expire in 90 days and need to be renewed before then. In the following example, add a new service ( certbot-cloudflare-renew ) into docker-compose.yml that will handle certificate renewals: services : certbot-cloudflare-renew : image : certbot/dns-cloudflare:latest command : renew --dns-cloudflare --dns-cloudflare-credentials /run/secrets/cloudflare-api-token volumes : - ./docker-data/certbot/certs/:/etc/letsencrtypt/ - ./docker-data/certbot/logs/:/var/log/letsencrypt/ secrets : - cloudflare-api-token You can manually run this service to renew the cert within 90 days: docker-compose run certbot-cloudflare-renew You should see the following output (The following log was generated with --dry-run options) Saving debug log to /var/log/letsencrypt/letsencrypt.log - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Processing /etc/letsencrypt/renewal/mail.example.com.conf - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Account registered.

You could use the Certbot --webroot feature, but it is more common to leverage a reverse proxy that manages the provisioning and renewal of certificates for your services automatically. In the following example, we show how docker-mailserver can be run alongside the docker containers nginx-proxy and acme-companion ( Referencing: acme-companion documentation ): Start the reverse proxy ( nginx-proxy ): docker run --detach \\ --name nginx-proxy \\ --restart always \\ --publish 80 :80 \\ --publish 443 :443 \\ --volume \" ${ PWD } /docker-data/nginx-proxy/html/:/usr/share/nginx/html/\" \\ --volume \" ${ PWD } /docker-data/nginx-proxy/vhost.d/:/etc/nginx/vhost.d/\" \\ --volume \" ${ PWD } /docker-data/acme-companion/certs/:/etc/nginx/certs/:ro\" \\ --volume '/var/run/docker.sock:/tmp/docker.sock:ro' \\ nginxproxy/nginx-proxy Then start the certificate provisioner ( acme-companion ), which will provide certificates to nginx-proxy : # Inherit `nginx-proxy` volumes via `--volumes-from`, but make `certs/` writeable: docker run --detach \\ --name nginx-proxy-acme \\ --restart always \\ --volumes-from nginx-proxy \\ --volume \" ${ PWD } /docker-data/acme-companion/certs/:/etc/nginx/certs/:rw\" \\ --volume \" ${ PWD } /docker-data/acme-companion/acme-state/:/etc/acme.sh/\" \\ --volume '/var/run/docker.sock:/var/run/docker.sock:ro' \\ --env 'DEFAULT_EMAIL=admin@example.com' \\ nginxproxy/acme-companion Start the rest of your web server containers as usual. Start a dummy container to provision certificates for your FQDN (eg: mail.example.com ). acme-companion will detect the container and generate a Let's Encrypt certificate for your domain, which can be used by docker-mailserver : docker run --detach \\ --name webmail \\ --env 'VIRTUAL_HOST=mail.example.com' \\ --env 'LETSENCRYPT_HOST=mail.example.com' \\ --env 'LETSENCRYPT_EMAIL=admin@example.com' \\ nginx You may want to add --env LETSENCRYPT_TEST=true to the above while testing, to avoid the Let's Encrypt certificate generation rate limits. Make sure your mount path to the letsencrypt certificates directory is correct. Edit your docker-compose.yml for the mailserver service to have volumes added like below: volumes : - ./docker-data/dms/mail-data/:/var/mail/ - ./docker-data/dms/mail-state/:/var/mail-state/ - ./docker-data/dms/config/:/tmp/docker-mailserver/ - ./docker-data/acme-companion/certs/:/etc/letsencrypt/live/:ro Then from the docker-compose.yml project directory, run: docker-compose up -d mailserver . Example using nginx-proxy and acme-companion with docker-compose The following example is the basic setup you need for using nginx-proxy and acme-companion with docker-mailserver ( Referencing: acme-companion documentation ): Example: docker-compose.yml You should have an existing docker-compose.yml with a mailserver service. Below are the modifications to add for integrating with nginx-proxy and acme-companion services: version : '3.8' services : # Add the following `environment` and `volumes` to your existing `mailserver` service: mailserver : environment : # SSL_TYPE: Uses the `letsencrypt` method to find mounted certificates. # VIRTUAL_HOST: The FQDN that `nginx-proxy` will configure itself to handle for HTTP[S] connections. # LETSENCRYPT_HOST: The FQDN for a certificate that `acme-companion` will provision and renew. - SSL_TYPE=letsencrypt - VIRTUAL_HOST=mail.example.com - LETSENCRYPT_HOST=mail.example.com volumes : - ./docker-data/acme-companion/certs/:/etc/letsencrypt/live/:ro # If you don't yet have your own `nginx-proxy` and `acme-companion` setup, # here is an example you can use: reverse-proxy : image : nginxproxy/nginx-proxy container_name : nginx-proxy restart : always ports : # Port 80: Required for HTTP-01 challenges to `acme-companion`. # Port 443: Only required for containers that need access over HTTPS. TLS-ALPN-01 challenge not supported. - \"80:80\" - \"443:443\" volumes : # `certs/`: Managed by the `acme-companion` container (_read-only_). # `docker.sock`: Required to interact with containers via the Docker API. # `dhparam`: A named data volume to prevent `nginx-proxy` creating an anonymous volume each time. - ./docker-data/nginx-proxy/html/:/usr/share/nginx/html/ - ./docker-data/nginx-proxy/vhost.d/:/etc/nginx/vhost.d/ - ./docker-data/acme-companion/certs/:/etc/nginx/certs/:ro - /var/run/docker.sock:/tmp/docker.sock:ro - dhparam:/etc/nginx/dhparam acme-companion : image : nginxproxy/acme-companion container_name : nginx-proxy-acme restart : always environment : # Only docker-compose v2 supports: `volumes_from: [nginx-proxy]`, # reference the _reverse-proxy_ `container_name` here: - NGINX_PROXY_CONTAINER=nginx-proxy volumes : # `html/`: Write ACME HTTP-01 challenge files that `nginx-proxy` will serve. # `vhost.d/`: To enable web access via `nginx-proxy` to HTTP-01 challenge files. # `certs/`: To store certificates and private keys. # `acme-state/`: To persist config and state for the ACME provisioner (`acme.sh`). # `docker.sock`: Required to interact with containers via the Docker API. - ./docker-data/nginx-proxy/html/:/usr/share/nginx/html/ - ./docker-data/nginx-proxy/vhost.d/:/etc/nginx/vhost.d/ - ./docker-data/acme-companion/certs/:/etc/nginx/certs/:rw - ./docker-data/acme-companion/acme-state/:/etc/acme.sh/ - /var/run/docker.sock:/var/run/docker.sock:ro # Once `nginx-proxy` fixes their Dockerfile, this named data volume can be removed from docs. # Users can opt for a local bind mount volume like all others if they prefer, but this volume # is only intended to be temporary. volumes : dhparam : Optional ENV vars worth knowing about Per container ENV that acme-companion will detect to override default provisioning settings: LETSENCRYPT_TEST=true : Recommended during initial setup . Otherwise the default production endpoint has a rate limit of 5 duplicate certificates per week . Overrides ACME_CA_URI to use the Let's Encrypt staging endpoint. LETSENCRYPT_EMAIL : For when you don't use DEFAULT_EMAIL on acme-companion , or want to assign a different email contact for this container. LETSENCRYPT_KEYSIZE : Allows you to configure the type (RSA or ECDSA) and size of the private key for your certificate. Default is RSA 4096. LETSENCRYPT_RESTART_CONTAINER=true : When the certificate is renewed, the entire container will be restarted to ensure the new certificate is used. acme-companion ENV for default settings that apply to all containers using LETSENCRYPT_HOST : DEFAULT_EMAIL : An email address that the CA ( eg: Let's Encrypt ) can contact you about expiring certificates, failed renewals, or for account recovery. You may want to use an email address not handled by your mail-server to ensure deliverability in the event your mail-server breaks. CERTS_UPDATE_INTERVAL : If you need to adjust the frequency to check for renewals. 3600 seconds (1 hour) by default. DEBUG=1 : Should be helpful when troubleshooting provisioning issues from acme-companion logs. ACME_CA_URI : Useful in combination with CA_BUNDLE to use a private CA. To change the default Let's Encrypt endpoint to the staging endpoint, use https://acme-staging-v02.api.letsencrypt.org/directory . CA_BUNDLE : If you want to use a private CA instead of Let's Encrypt . Alternative to required ENV on mailserver service While you will still need both nginx-proxy and acme-companion containers, you can manage certificates without adding ENV vars to containers. Instead the ENV is moved into a file and uses the acme-companion feature Standalone certificates . This requires adding another shared volume between nginx-proxy and acme-companion : services : reverse-proxy : volumes : - ./docker-data/nginx-proxy/conf.d/:/etc/nginx/conf.d/ acme-companion : volumes : - ./docker-data/nginx-proxy/conf.d/:/etc/nginx/conf.d/ - ./docker-data/acme-companion/standalone.sh:/app/letsencrypt_user_data:ro acme-companion mounts a shell script ( standalone.sh ), which defines variables to customize certificate provisioning: # A list IDs for certificates to provision: LETSENCRYPT_STANDALONE_CERTS =( 'mail' ) # Each ID inserts itself into the standard `acme-companion` supported container ENV vars below. # The LETSENCRYPT_<ID>_HOST var is a list of FQDNs to provision a certificate for as the SAN field: LETSENCRYPT_mail_HOST =( 'mail.example.com' ) # Optional variables: LETSENCRYPT_mail_TEST = true LETSENCRYPT_mail_EMAIL = 'admin@example.com' # RSA-4096 => `4096`, ECDSA-256 => `ec-256`: LETSENCRYPT_mail_KEYSIZE = 4096 Unlike with the equivalent ENV for containers, changes to this file will not be detected automatically . You would need to wait until the next renewal check by acme-companion ( every hour by default ), restart acme-companion , or manually invoke the service loop : docker exec nginx-proxy-acme /app/signal_le_service Example using Let's Encrypt Certificates with a Synology NAS Version 6.2 and later of the Synology NAS DSM OS now come with an interface to generate and renew letencrypt certificates. Navigation into your DSM control panel and go to Security, then click on the tab Certificate to generate and manage letsencrypt certificates. Amongst other things, you can use these to secure your mail-server. DSM locates the generated certificates in a folder below /usr/syno/etc/certificate/_archive/ . Navigate to that folder and note the 6 character random folder name of the certificate you'd like to use. Then, add the following to your docker-compose.yml declaration file: # Note: If you have an existing setup that was working pre docker-mailserver v10.2, # '/tmp/dms/custom-certs' below has replaced the previous '/tmp/ssl' container path. volumes : - /usr/syno/etc/certificate/_archive/<your-folder>/:/tmp/dms/custom-certs/ environment : - SSL_TYPE=manual - SSL_CERT_PATH=/tmp/dms/custom-certs/fullchain.pem - SSL_KEY_PATH=/tmp/dms/custom-certs/privkey.pem DSM-generated letsencrypt certificates get auto-renewed every three months. Caddy If you are using Caddy to renew your certificates, please note that only RSA certificates work. Read #1440 for details. In short for Caddy v1 the Caddyfile should look something like: https://mail.example.com { tls admin@example.com { key_type rsa2048 } } For Caddy v2 you can specify the key_type in your server's global settings, which would end up looking something like this if you're using a Caddyfile : { debug admin localhost:2019 http_port 80 https_port 443 default_sni example.com key_type rsa4096 } If you are instead using a json config for Caddy v2, you can set it in your site's TLS automation policies: Example Code { \"apps\" : { \"http\" : { \"servers\" : { \"srv0\" : { \"listen\" : [ \":443\" ], \"routes\" : [ { \"match\" : [ { \"host\" : [ \"mail.example.com\" , ] } ], \"handle\" : [ { \"handler\" : \"subroute\" , \"routes\" : [ { \"handle\" : [ { \"body\" : \"\" , \"handler\" : \"static_response\" } ] } ] } ], \"terminal\" : true }, ] } } }, \"tls\" : { \"automation\" : { \"policies\" : [ { \"subjects\" : [ \"mail.example.com\" , ], \"key_type\" : \"rsa2048\" , \"issuer\" : { \"email\" : \"admin@example.com\" , \"module\" : \"acme\" } }, { \"issuer\" : { \"email\" : \"admin@example.com\" , \"module\" : \"acme\" } } ] } } } } The generated certificates can be mounted: volumes : - ${CADDY_DATA_DIR}/certificates/acme-v02.api.letsencrypt.org-directory/mail.example.com/mail.example.com.crt:/etc/letsencrypt/live/mail.example.com/fullchain.pem - ${CADDY_DATA_DIR}/certificates/acme-v02.api.letsencrypt.org-directory/mail.example.com/mail.example.com.key:/etc/letsencrypt/live/mail.example.com/privkey.pem EC certificates fail in the TLS handshake: CONNECTED(00000003) 140342221178112:error:14094410:SSL routines:ssl3_read_bytes:sslv3 alert handshake failure:ssl/record/rec_layer_s3.c:1543:SSL alert number 40 no peer certificate available No client certificate CA names sent Traefik v2 Traefik is an open-source application proxy using the ACME protocol . Traefik can request certificates for domains and subdomains, and it will take care of renewals, challenge negotiations, etc. We strongly recommend to use Traefik 's major version 2. Traefik 's storage format is natively supported if the acme.json store is mounted into the container at /etc/letsencrypt/acme.json . The file is also monitored for changes and will trigger a reload of the mail services (Postfix and Dovecot). Wildcard certificates are supported. If your FQDN is mail.example.com and your wildcard certificate is *.example.com , add the ENV: SSL_DOMAIN = example.com . The mail-server will select it's certificate from acme.json checking these ENV for a matching FQDN ( in order of priority ): ${ SSL_DOMAIN } ${ HOSTNAME } ${ DOMAINNAME } This setup only comes with one caveat: The domain has to be configured on another service for Traefik to actually request it from Let's Encrypt , i.e. Traefik will not issue a certificate without a service / router demanding it. Example Code Here is an example setup for docker-compose : version : '3.8' services : mailserver : image : docker.io/mailserver/docker-mailserver:latest container_name : mailserver hostname : mail domainname : example.com volumes : - ./docker-data/traefik/acme.json:/etc/letsencrypt/acme.json:ro environment : SSL_TYPE : letsencrypt SSL_DOMAIN : mail.example.com # for a wildcard certificate, use # SSL_DOMAIN: example.com reverse-proxy : image : docker.io/traefik:latest #v2.5 container_name : docker-traefik ports : - \"80:80\" - \"443:443\" command : - --providers.docker - --entrypoints.http.address=:80 - --entrypoints.http.http.redirections.entryPoint.to=https - --entrypoints.http.http.redirections.entryPoint.scheme=https - --entrypoints.https.address=:443 - --entrypoints.https.http.tls.certResolver=letsencrypt - --certificatesresolvers.letsencrypt.acme.email=admin@example.com - --certificatesresolvers.letsencrypt.acme.storage=/acme.json - --certificatesresolvers.letsencrypt.acme.httpchallenge.entrypoint=http volumes : - ./docker-data/traefik/acme.json:/acme.json - /var/run/docker.sock:/var/run/docker.sock:ro whoami : image : docker.io/traefik/whoami:latest labels : - \"traefik.http.routers.whoami.rule=Host(`mail.example.com`)\" Self-Signed Certificates Warning Use self-signed certificates only for testing purposes! This feature requires you to provide the following files into your docker-data/dms/config/ssl/ directory ( internal location: /tmp/docker-mailserver/ssl/ ): <FQDN>-key.pem <FQDN>-cert.pem demoCA/cacert.pem Where <FQDN> is the FQDN you've configured for your docker-mailserver container. Add SSL_TYPE=self-signed to your docker-mailserver environment variables. Postfix and Dovecot will be configured to use the provided certificate ( .pem files above ) during container startup. Generating a self-signed certificate Note Since docker-mailserver v10, support in setup.sh for generating a self-signed SSL certificate internally was removed. One way to generate self-signed certificates is with Smallstep's step CLI . This is exactly what docker-mailserver does for creating test certificates . For example with the FQDN mail.example.test , you can generate the required files by running: #! /bin/sh mkdir -p demoCA step certificate create \"Smallstep Root CA\" \"demoCA/cacert.pem\" \"demoCA/cakey.pem\" \\ --no-password --insecure \\ --profile root-ca \\ --not-before \"2021-01-01T00:00:00+00:00\" \\ --not-after \"2031-01-01T00:00:00+00:00\" \\ --san \"example.test\" \\ --san \"mail.example.test\" \\ --kty RSA --size 2048 step certificate create \"Smallstep Leaf\" mail.example.test-cert.pem mail.example.test-key.pem \\ --no-password --insecure \\ --profile leaf \\ --ca \"demoCA/cacert.pem\" \\ --ca-key \"demoCA/cakey.pem\" \\ --not-before \"2021-01-01T00:00:00+00:00\" \\ --not-after \"2031-01-01T00:00:00+00:00\" \\ --san \"example.test\" \\ --san \"mail.example.test\" \\ --kty RSA --size 2048 If you'd rather not install the CLI tool locally to run the step commands above; you can save the script above to a file such as generate-certs.sh ( and make it executable chmod +x generate-certs.sh ) in a directory that you want the certs to be placed (eg: docker-data/dms/custom-certs/ ), then use docker to run that script in a container: # '--user' is to keep ownership of the files written to # the local volume to use your systems User and Group ID values. docker run --rm -it \\ --user \" $( id -u ) : $( id -g ) \" \\ --volume \" ${ PWD } /docker-data/dms/custom-certs/:/tmp/step-ca/\" \\ --workdir \"/tmp/step-ca/\" \\ --entrypoint \"/tmp/step-ca/generate-certs.sh\" \\ smallstep/step-ca Bring Your Own Certificates You can also provide your own certificate files. Add these entries to your docker-compose.yml : volumes : - ./docker-data/dms/custom-certs/:/tmp/dms/custom-certs/:ro environment : - SSL_TYPE=manual # Values should match the file paths inside the container: - SSL_CERT_PATH=/tmp/dms/custom-certs/public.crt - SSL_KEY_PATH=/tmp/dms/custom-certs/private.key This will mount the path where your certificate files reside locally into the read-only container folder: /tmp/dms/custom-certs . The local and internal paths may be whatever you prefer, so long as both SSL_CERT_PATH and SSL_KEY_PATH point to the correct internal file paths. The certificate files may also be named to your preference, but should be PEM encoded. SSL_ALT_CERT_PATH and SSL_ALT_KEY_PATH are additional ENV vars to support a 2nd certificate as a fallback. Commonly known as hybrid or dual certificate support. This is useful for using a modern ECDSA as your primary certificate, and RSA as your fallback for older connections. They work in the same manner as the non- ALT versions. Info You may have to restart docker-mailserver once the certificates change. Testing a Certificate is Valid From your host: docker exec mailserver openssl s_client \\ -connect 0 .0.0.0:25 \\ -starttls smtp \\ -CApath /etc/ssl/certs/ Or: docker exec mailserver openssl s_client \\ -connect 0 .0.0.0:143 \\ -starttls imap \\ -CApath /etc/ssl/certs/ And you should see the certificate chain, the server certificate and: Verify return code: 0 (ok) In addition, to verify certificate dates: docker exec mailserver openssl s_client \\ -connect 0 .0.0.0:25 \\ -starttls smtp \\ -CApath /etc/ssl/certs/ \\ 2 >/dev/null | openssl x509 -noout -dates Plain-Text Access Warning Not recommended for purposes other than testing. Add this to docker-data/dms/config/dovecot.cf : ssl = yes disable_plaintext_auth = no These options in conjunction mean: SSL/TLS is offered to the client, but the client isn't required to use it. The client is allowed to login with plaintext authentication even when SSL/TLS isn't enabled on the connection. This is insecure , because the plaintext password is exposed to the internet. Importing Certificates Obtained via Another Source If you have another source for SSL/TLS certificates you can import them into the server via an external script. The external script can be found here: external certificate import script . Only compatible with docker-mailserver releases < v10.2 The script expects /etc/postfix/ssl/cert and /etc/postfix/ssl/key files to be configured paths for both Postfix and Dovecot to use. Since the docker-mailserver 10.2 release, certificate files have moved to /etc/dms/tls/ , and the file name may differ depending on provisioning method. This third-party script also has fullchain.pem and privkey.pem as hard-coded, thus is incompatible with other filenames. Additionally it has never supported handling ALT fallback certificates (for supporting dual/hybrid, RSA + ECDSA). The steps to follow are these: Transfer the new certificates to ./docker-data/dms/custom-certs/ (volume mounted to: /tmp/ssl/ ) You should provide fullchain.key and privkey.pem Place the script in ./docker-data/dms/config/ (volume mounted to: /tmp/docker-mailserver/ ) Make the script executable ( chmod +x tomav-renew-certs.sh ) Run the script: docker exec mailserver /tmp/docker-mailserver/tomav-renew-certs.sh If an error occurs the script will inform you. If not you will see both postfix and dovecot restart. After the certificates have been loaded you can check the certificate: openssl s_client \\ -servername mail.example.com \\ -connect 192 .168.0.72:465 \\ 2 >/dev/null | openssl x509 # or openssl s_client \\ -servername mail.example.com \\ -connect mail.example.com:465 \\ 2 >/dev/null | openssl x509 Or you can check how long the new certificate is valid with commands like: export SITE_URL = \"mail.example.com\" export SITE_IP_URL = \"192.168.0.72\" # can also use `mail.example.com` export SITE_SSL_PORT = \"993\" # imap port dovecot ##works: check if certificate will expire in two weeks #2 weeks is 1209600 seconds #3 weeks is 1814400 #12 weeks is 7257600 #15 weeks is 9072000 certcheck_2weeks = ` openssl s_client -connect ${ SITE_IP_URL } : ${ SITE_SSL_PORT } \\ -servername ${ SITE_URL } 2 > /dev/null | openssl x509 -noout -checkend 1209600 ` #################################### #notes: output could be either: #Certificate will not expire #Certificate will expire #################### What does the script that imports the certificates do: Check if there are new certs in the internal container folder: /tmp/ssl . Check with the ssl cert fingerprint if they differ from the current certificates. If so it will copy the certs to the right places. And restart postfix and dovecot. You can of course run the script by cron once a week or something. In that way you could automate cert renewal.

These are standardized pre-defined DH groups and the only available DH groups for TLS 1.3. It is discouraged to generate your own DH parameters as it is often less secure. Despite this, if you must use non-standard DH parameters or you would like to swap ffdhe4096 for a different group (eg ffdhe2048 ); Add your own PEM encoded DH params file via a volume to /tmp/docker-mailserver/dhparams.pem .

The external script can be found here: external certificate import script . Only compatible with docker-mailserver releases < v10.2 The script expects /etc/postfix/ssl/cert and /etc/postfix/ssl/key files to be configured paths for both Postfix and Dovecot to use. Since the docker-mailserver 10.2 release, certificate files have moved to /etc/dms/tls/ , and the file name may differ depending on provisioning method. This third-party script also has fullchain.pem and privkey.pem as hard-coded, thus is incompatible with other filenames. Additionally it has never supported handling ALT fallback certificates (for supporting dual/hybrid, RSA + ECDSA). The steps to follow are these: Transfer the new certificates to ./docker-data/dms/custom-certs/ (volume mounted to: /tmp/ssl/ ) You should provide fullchain.key and privkey.pem Place the script in ./docker-data/dms/config/ (volume mounted to: /tmp/docker-mailserver/ ) Make the script executable ( chmod +x tomav-renew-certs.sh ) Run the script: docker exec mailserver /tmp/docker-mailserver/tomav-renew-certs.sh If an error occurs the script will inform you. If not you will see both postfix and dovecot restart. After the certificates have been loaded you can check the certificate: openssl s_client \\ -servername mail.example.com \\ -connect 192 .168.0.72:465 \\ 2 >/dev/null | openssl x509 # or openssl s_client \\ -servername mail.example.com \\ -connect mail.example.com:465 \\ 2 >/dev/null | openssl x509 Or you can check how long the new certificate is valid with commands like: export SITE_URL = \"mail.example.com\" export SITE_IP_URL = \"192.168.0.72\" # can also use `mail.example.com` export SITE_SSL_PORT = \"993\" # imap port dovecot ##works: check if certificate will expire in two weeks #2 weeks is 1209600 seconds #3 weeks is 1814400 #12 weeks is 7257600 #15 weeks is 9072000 certcheck_2weeks = ` openssl s_client -connect ${ SITE_IP_URL } : ${ SITE_SSL_PORT } \\ -servername ${ SITE_URL } 2 > /dev/null | openssl x509 -noout -checkend 1209600 ` #################################### #notes: output could be either: #Certificate will not expire #Certificate will expire #################### What does the script that imports the certificates do: Check if there are new certs in the internal container folder: /tmp/ssl . Check with the ssl cert fingerprint if they differ from the current certificates. If so it will copy the certs to the right places. And restart postfix and dovecot. You can of course run the script by cron once a week or something. In that way you could automate cert renewal. If you do so it is probably wise to run an automated check on certificate expiry as well. Such a check could look something like this: # This script is run inside docker-mailserver via 'docker exec ...', using the 'mail' command to send alerts. ## code below will alert if certificate expires in less than two weeks ## please adjust varables! ## make sure the 'mail -s' command works!

Prefer port 465 which provides Implicit TLS. Outbound Traffic (On the Right) Port 25: Send the email directly to the given email address MTA as possible.

Port 465( and 587 ): SMTP Relays are a popular choice to hand-off delivery of email through. Services like SendGrid are useful for bulk email(marketing) or when your webhost or ISP are preventing you from using standard ports like port 25 to send out email(which can be abused by spammers). docker-mailserver can serve as a relay too, but the difference between a DIY relay and a professional service is reputation, which is referenced by MTAs you're delivering to such as Outlook, Gmail or others(perhaps another docker-mailserver server!), when deciding if email should be marked as junked or potentially not delivered at all. As a service like SendGrid has a reputation to maintain, relay is restricted to registered users who must authenticate(even on port 25), they do not store email, merely forward it to another MTA which could be delivered on a different port like 25. Explicit vs Implicit TLS Explicit TLS (aka Opportunistic TLS) - Opt-in Encryption Communication on these ports begin in cleartext , indicating support for STARTTLS . If both client and server support STARTTLS the connection will be secured over TLS, otherwise the connection is unable to use encryption to secure it. By default, docker-mailserver is configured to reject connections that fail to establish a secure connection when authentication is required, rather than allow an insecure connection ( Port 25 will allow receiving unencrypted deliveries which doesn't require authentication ). Support for STARTTLS is not always implemented correctly, which can lead to leaking credentials(client sending too early) prior to a TLS connection being established. Third-parties such as some ISPs have also been known to intercept the STARTTLS exchange, modifying network traffic to prevent establishing a secure connection. Due to these security concerns, RFC 8314 (Section 4.1) encourages you to prefer Implicit TLS ports where possible . Implicit TLS - Enforced Encryption Communication is always encrypted, avoiding the above mentioned issues with Explicit TLS. You may know of these ports as SMTPS, POP3S, IMAPS , which indicate the protocol in combination with a TLS connection. However, Explicit TLS ports provide the same benefit when STARTTLS is successfully negotiated; Implicit TLS better communicates the improved security to all three protocols (SMTP/POP3/IMAP over Implicit TLS). Additionally, referring to port 465 as SMTPS would be incorrect, as it is a submissions port requiring authentication to proceed via ESMTP , whereas ESMTPS has a different meaning(STARTTLS supported). Port 25 may lack Implicit TLS, but can be configured to be more secure between trusted parties via MTA-STS, STARTTLS Policy List, DNSSEC and DANE.

For example, the following docker-data/dms/config/postfix-regexp.cf causes all email sent to \"test\" users to be delivered to qa@example.com instead: /^test[0-9][0-9]*@example.com/ qa@example.com Address Tags (Extension Delimiters) an Alternative to Aliases Postfix supports so-called address tags, in the form of plus (+) tags - i.e. address+tag@example.com will end up at address@example.com . This is configured by default and the (configurable !) separator is set to + . For more info, see the official documentation . Note If you do decide to change the configurable separator, you must add the same line to both docker-data/dms/config/postfix-main.cf and docker-data/dms/config/dovecot.cf , because Dovecot is acting as the delivery agent.

All tests and associated configuration is stored in the test/ directory. If you want to change existing functionality or integrate a new feature into DMS, you will probably need to work with our test suite. Can I use macOS? We do not support running linting, tests, etc. on macOS at this time. Please use a Linux VM, Debian/Ubuntu is recommended. About We use BATS ( Bash Automated Testing System ) and additional support libraries. BATS is very similar to Bash, and one can easily and quickly get an understanding of how tests in a single file are run. A test file template provides a minimal working example for newcomers to look at. Structure The test/ directory contains multiple directories. Among them is the bats/ directory ( which is the BATS git submodule ) and the helper/ directory. The latter is especially interesting because it contains common support functionality used in almost every test. Actual tests are located in test/tests/ . Test suite undergoing refactoring We are currently in the process of restructuring all of our tests. Tests will be moved into test/tests/parallel/ and new tests should be placed there as well. Using Our Helper Functions There are many functions that aid in writing tests. We urge you to use them! They will not only ease writing a test but they will also do their best to ensure there are no race conditions or other unwanted side effects. To learn about the functions we provide, you can: look into existing tests for helper functions we already used look into the test/helper/ directory which contains all files that can (and will) be loaded in test files We encourage you to try both of the approaches mentioned above. To make understanding and using the helper functions easy, every function contains detailed documentation comments. Read them carefully! How Are Tests Run? Tests are split into two categories: test/tests/parallel/ : Multiple test files are run concurrently to reduce the required time to complete the test suite. A test file will presently run it's own defined test-cases in a sequential order. test/tests/serial/ : Each test file is queued up to run sequentially. Tests that are unable to support running concurrently belong here. Parallel tests are further partitioned into smaller sets. If your system has the resources to support running more than one of those sets at a time this is perfectly ok ( our CI runs tests by distributing the sets across multiple test runners ). Care must be taken not to mix running the serial tests while a parallel set is also running; this is handled for you when using make tests . Running Tests Prerequisites To run the test suite, you will need to: Install Docker Install jq and (GNU) parallel (under Ubuntu, use sudo apt-get -y install jq parallel ) Execute git submodule update --init --recursive if you haven't already initialized the git submodules Executing Test(s) We use make to run commands. Run make build to create or update the local mailserver-testing:ci Docker image ( using the projects Dockerfile ) Run all tests: make clean tests Run a single test: make clean generate-accounts test/<TEST NAME WITHOUT .bats SUFFIX> Run multiple unrelated tests: make clean generate-accounts test/<TEST NAME WITHOUT .bats SUFFIX>,<TEST NAME WITHOUT .bats SUFFIX> (just add a , and then immediately write the new test name) Run a whole set or all serial tests: make clean generate-accounts tests/parallel/setX where X is the number of the set or make clean generate-accounts tests/serial Setting the Degree of Parallelization for Tests If your machine is capable, you can increase the amount of tests that are run simultaneously by prepending the make clean all command with BATS_PARALLEL_JOBS=X (i.e. BATS_PARALLEL_JOBS=X make clean all ). This wil speed up the test procedure. You can also run all tests in serial by setting BATS_PARALLEL_JOBS=1 this way. The default value of BATS_PARALLEL_JOBS is 2. This can be increased if your system has the resources spare to support running more jobs at once to complete the test suite sooner. Test Output when Running in Parallel When running tests in parallel ( with make clean generate-accounts tests/parallel/setX ), BATS will delay outputting the results until completing all test cases within a file. This likewise delays the reporting of test-case failures. When troubleshooting parallel set tests, you may prefer to run specific tests you're working on serially ( as demonstrated in the example below ). When writing tests, ensure that parallel set tests still pass when run in parallel. You need to account for other tests running in parallel that may interfere with your own tests logic. An Example In this example, you've made a change to the Rspamd feature support ( or adjusted it's tests ). First verify no regressions have been introduced by running it's specific test file: $ make clean generate-accounts test/rspamd rspamd.bats \u2713 [Rspamd] Postfix's main.cf was adjusted [12] \u2713 [Rspamd] normal mail passes fine [44] \u2713 [Rspamd] detects and rejects spam [122] \u2713 [Rspamd] detects and rejects virus [189] As your feature work progresses your change for Rspamd also affects ClamAV. As your change now spans more than just the Rspamd test file, you could run multiple test files serially: $ make clean generate-accounts test/rspamd,clamav rspamd.bats \u2713 [Rspamd] Postfix's main.cf was adjusted [12] \u2713 [Rspamd] normal mail passes fine [44] \u2713 [Rspamd] detects and rejects spam [122] \u2713 [Rspamd] detects and rejects virus [189] clamav.bats \u2713 [ClamAV] log files exist at /var/log/mail directory [68] \u2713 [ClamAV] should be identified by Amavis [67] \u2713 [ClamAV] freshclam cron is enabled [76] \u2713 [ClamAV] env CLAMAV_MESSAGE_SIZE_LIMIT is set correctly [63] \u2713 [ClamAV] rejects virus [60] You're almost finished with your change before submitting it as a PR. It's a good idea to run the full parallel set those individual tests belong to ( especially if you've modified any tests ): $ make clean generate-accounts tests/parallel/set1 default_relay_host.bats \u2713 [Relay] (ENV) 'DEFAULT_RELAY_HOST' should configure 'main.cf:relayhost' [88] spam_virus/amavis.bats \u2713 [Amavis] SpamAssassin integration should be active [1165] spam_virus/clamav.bats \u2713 [ClamAV] log files exist at /var/log/mail directory [73] \u2713 [ClamAV] should be identified by Amavis [67] \u2713 [ClamAV] freshclam cron is enabled [76] ...

Please let us know via a Github Issue if you're having any difficulty following the guide so that we can update it. This guide is focused on only using SMTP ports (not POP3 and IMAP) with the intent to send received mail to another MTA service such as Gmail . It is not intended to have a MUA client ( eg: Thunderbird ) to retrieve mail directly from docker-mailserver via POP3/IMAP. In this setup docker-mailserver is not intended to receive email externally, so no anti-spam or anti-virus software is needed, making the service lighter to run. Open Relays Adding the docker network's gateway to the list of trusted hosts ( eg: using the network or connected-networks option ), can create an open relay . For instance if IPv6 is enabled on the host machine, but not in Docker . If you're running a version of docker-mailserver earlier than v10.2, you'll need to get setup.sh . Otherwise you can substitute ./setup.sh <command> with docker exec mailserver setup <command> . Pull the docker image: docker pull docker.io/mailserver/docker-mailserver:latest . Create the file docker-compose.yml with a content like this: Example services : mailserver : image : docker.io/mailserver/docker-mailserver:latest container_name : mailserver # Provide the FQDN of your mail server here (Your DNS MX record should point to this value) hostname : mail.example.com ports : - \"25:25\" - \"587:587\" - \"465:465\" volumes : - ./docker-data/dms/mail-data/:/var/mail/ - ./docker-data/dms/mail-state/:/var/mail-state/ - ./docker-data/dms/mail-logs/:/var/log/mail/ - ./docker-data/dms/config/:/tmp/docker-mailserver/ - /etc/localtime:/etc/localtime:ro environment : - ENABLE_FAIL2BAN=1 # Using letsencrypt for SSL/TLS certificates - SSL_TYPE=letsencrypt # Allow sending emails from other docker containers # Beware creating an Open Relay: https://docker-mailserver.github.io/docker-mailserver/latest/config/environment/#permit_docker - PERMIT_DOCKER=network # You may want to enable this: https://docker-mailserver.github.io/docker-mailserver/latest/config/environment/#spoof_protection # See step 8 below, which demonstrates setup with enabled/disabled SPOOF_PROTECTION: - SPOOF_PROTECTION=0 cap_add : - NET_ADMIN # For Fail2Ban to work restart : always The docs have a detailed page on Environment Variables for reference. Firewalled ports You may need to open ports 25 , 587 and 465 on the firewall. For example, with the firewall ufw , run: ufw allow 25 ufw allow 587 ufw allow 465 Configure your DNS service to use an MX record for the hostname (eg: mail ) you configured in the previous step and add the SPF TXT record. If you manually manage the DNS zone file for the domain, it would look something like this: mail IN A 10.11.12.13 ; mail-server for example.com 3600 IN MX 1 mail.example.com. ; Add SPF record IN TXT \"v=spf1 mx ~all\" Then don't forget to change the serial number and to restart the service. Generate DKIM keys for your domain via ./setup.sh config dkim . Copy the content of the file docker-data/dms/config/opendkim/keys/example.com/mail.txt and add it to your DNS records as a TXT like SPF was handled above.

Please let us know via a Github Issue if you're having any difficulty following the guide so that we can update it. This guide is focused on only using SMTP ports (not POP3 and IMAP) with the intent to send received mail to another MTA service such as Gmail . It is not intended to have a MUA client ( eg: Thunderbird ) to retrieve mail directly from docker-mailserver via POP3/IMAP. In this setup docker-mailserver is not intended to receive email externally, so no anti-spam or anti-virus software is needed, making the service lighter to run. Open Relays Adding the docker network's gateway to the list of trusted hosts ( eg: using the network or connected-networks option ), can create an open relay . For instance if IPv6 is enabled on the host machine, but not in Docker . If you're running a version of docker-mailserver earlier than v10.2, you'll need to get setup.sh . Otherwise you can substitute ./setup.sh <command> with docker exec mailserver setup <command> . Pull the docker image: docker pull docker.io/mailserver/docker-mailserver:latest . Create the file docker-compose.yml with a content like this: Example services : mailserver : image : docker.io/mailserver/docker-mailserver:latest container_name : mailserver # Provide the FQDN of your mail server here (Your DNS MX record should point to this value) hostname : mail.example.com ports : - \"25:25\" - \"587:587\" - \"465:465\" volumes : - ./docker-data/dms/mail-data/:/var/mail/ - ./docker-data/dms/mail-state/:/var/mail-state/ - ./docker-data/dms/mail-logs/:/var/log/mail/ - ./docker-data/dms/config/:/tmp/docker-mailserver/ - /etc/localtime:/etc/localtime:ro environment : - ENABLE_FAIL2BAN=1 # Using letsencrypt for SSL/TLS certificates - SSL_TYPE=letsencrypt # Allow sending emails from other docker containers # Beware creating an Open Relay: https://docker-mailserver.github.io/docker-mailserver/latest/config/environment/#permit_docker - PERMIT_DOCKER=network # You may want to enable this: https://docker-mailserver.github.io/docker-mailserver/latest/config/environment/#spoof_protection # See step 8 below, which demonstrates setup with enabled/disabled SPOOF_PROTECTION: - SPOOF_PROTECTION=0 cap_add : - NET_ADMIN # For Fail2Ban to work restart : always The docs have a detailed page on Environment Variables for reference. Firewalled ports You may need to open ports 25 , 587 and 465 on the firewall. For example, with the firewall ufw , run: ufw allow 25 ufw allow 587 ufw allow 465 Configure your DNS service to use an MX record for the hostname (eg: mail ) you configured in the previous step and add the SPF TXT record. If you manually manage the DNS zone file for the domain, it would look something like this: mail IN A 10.11.12.13 ; mail-server for example.com 3600 IN MX 1 mail.example.com. ; Add SPF record IN TXT \"v=spf1 mx ~all\" Then don't forget to change the serial number and to restart the service. Generate DKIM keys for your domain via ./setup.sh config dkim . Copy the content of the file docker-data/dms/config/opendkim/keys/example.com/mail.txt and add it to your DNS records as a TXT like SPF was handled above.

The settings for this on mailserver.env are: ENABLE_LDAP = 1 # with the :edge tag, use ACCOUNT_PROVISIONER ACCOUNT_PROVISIONER = LDAP LDAP_START_TLS = yes LDAP_SERVER_HOST = ldap.example.org LDAP_SEARCH_BASE = ou=users,dc=example,dc=org LDAP_BIND_DN = cn=mailserver,dc=example,dc=org LDAP_BIND_PW = pass1234 ENABLE_SASLAUTHD = 1 SASLAUTHD_MECHANISMS = ldap SASLAUTHD_LDAP_SERVER = ldap.example.org SASLAUTHD_LDAP_START_TLS = yes SASLAUTHD_LDAP_BIND_DN = cn=mailserver,dc=example,dc=org SASLAUTHD_LDAP_PASSWORD = pass1234 SASLAUTHD_LDAP_SEARCH_BASE = ou=users,dc=example,dc=org SASLAUTHD_LDAP_FILTER = (&(uid=%U)(objectClass=inetOrgPerson)) My LDAP data structure is very basic, containing only the username, password, and the external email address where to forward emails for this user. An entry looks like this: add uid = username,ou=users,dc=example,dc=org uid : username objectClass : inetOrgPerson sn : username cn : username userPassword : {SSHA}abcdefghi123456789 email : external-account@gmail.com This structure is different from what is expected/assumed from the configuration scripts of docker-mailserver , so it doesn't work just by using the LDAP_QUERY_FILTER_... settings. Instead, I had to use a custom configuration ( via user-patches.sh ). I created the script docker-data/dms/config/user-patches.sh , with content like this: #!/bin/bash rm -f /etc/postfix/ { ldap-groups.cf,ldap-domains.cf } postconf \\ \"virtual_mailbox_domains = /etc/postfix/vhost\" \\ \"virtual_alias_maps = ldap:/etc/postfix/ldap-aliases.cf texthash:/etc/postfix/virtual\" \\ \"smtpd_sender_login_maps = ldap:/etc/postfix/ldap-users.cf\" sed -i /etc/postfix/ldap-users.cf \\ -e '/query_filter/d' \\ -e '/result_attribute/d' \\ -e '/result_format/d' cat <<EOF >> /etc/postfix/ldap-users.cf query_filter = (uid=%u) result_attribute = uid result_format = %s@example.org EOF sed -i /etc/postfix/ldap-aliases.cf \\ -e '/domain/d' \\ -e '/query_filter/d' \\ -e '/result_attribute/d' cat <<EOF >> /etc/postfix/ldap-aliases.cf domain = example.org query_filter = (uid=%u) result_attribute = mail EOF postfix reload You see that besides query_filter , I had to customize as well result_attribute and result_format .

It's a piece of software dedicated to accepting submitted emails, then forwarding them-where exactly will depend on an email's final destination. If the receiving MTA is responsible for the FQDN the email is sent to, then an MTA is to forward that email to an MDA (see below). Otherwise, it is to transfer (ie. forward, relay) to another MTA, \"closer\" to the email's final destination.</li> <li>MDA: a Mail Delivery Agent is responsible for accepting emails from an MTA and dropping them into their recipients' mailboxes, whichever the form.</li> </ul> <p>Here's a schematic view of mail delivery:</p> <pre><code>Sending an email:    MUA ----&gt; MTA ----&gt; (MTA relays) ----&gt; MDA\nFetching an email:   MUA &lt;--------------------------------- MDA\n</code></pre> <p>There may be other moving parts or sub-divisions (for instance, at several points along the chain, specialized programs may be analyzing, filtering, bouncing, editing\u2026 the exchanged emails).</p> <p>In a nutshell, <code>docker-mailserver</code> provides you with the following components:</p> <ul> <li>A MTA: Postfix</li> <li>A MDA: Dovecot</li> <li>A bunch of additional programs to improve security and emails processing</li> </ul> <p>Here's where <code>docker-mailserver</code>'s toochain fits within the delivery chain:</p> <pre><code>                                    docker-mailserver is here:\n                                                         \u250f\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u2513\nSending an email:    MUA ---&gt; MTA ---&gt; (MTA relays) ---&gt; \u252b MTA \u256e \u2503\nFetching an email:   MUA &lt;------------------------------ \u252b MDA \u256f \u2503\n                                                         \u2517\u2501\u2501\u2501\u2501\u2501\u2501\u2501\u251b\n</code></pre> An Example <p>Let's say Alice owns a Gmail account, <code>alice@gmail.com</code>; and Bob owns an account on a <code>docker-mailserver</code>'s instance, <code>bob@dms.io</code>.</p> <p>Make sure not to conflate these two very different scenarios: A) Alice sends an email to <code>bob@dms.io</code> =&gt; the email is first submitted to MTA <code>smtp.gmail.com</code>, then relayed to MTA <code>smtp.dms.io</code> where it is then delivered into Bob's mailbox. B) Bob sends an email to <code>alice@gmail.com</code> =&gt; the email is first submitted to MTA <code>smtp.dms.io</code>, then relayed to MTA <code>smtp.gmail.com</code> and eventually delivered into Alice's mailbox.</p> <p>In scenario A the email leaves Gmail's premises, that email's initial submission is not handled by your <code>docker-mailserver</code> instance(MTA); it merely receives the email after it has been relayed by Gmail's MTA. In scenario B, the <code>docker-mailserver</code> instance(MTA) handles the submission, prior to relaying.</p> <p>The main takeaway is that when a third-party sends an email to a <code>docker-mailserver</code> instance(MTA) (or any MTA for that matter), it does not establish a direct connection with that MTA. Email submission first goes through the sender's MTA, then some relaying between at least two MTAs is required to deliver the email. That will prove very important when it comes to security management.</p> <p>One important thing to note is that MTA and MDA programs may actually handle multiple tasks (which is the case with <code>docker-mailserver</code>'s Postfix and Dovecot).</p> <p>For instance, Postfix is both an SMTP server (accepting emails) and a relaying MTA (transferring, ie. sending emails to other MTA/MDA); Dovecot is both an MDA (delivering emails in mailboxes) and an IMAP server (allowing MUAs to fetch emails from the mail server). On top of that, Postfix may rely on Dovecot's authentication capabilities.</p> <p>The exact relationship between all the components and their respective (sometimes shared) responsibilities is beyond the scope of this document.

Long story short: this is incorrect and should be avoided.</p> <p>Although a very satisfactory setup, Implicit TLS on port 465 is somewhat \"cutting edge\". There exists another well established mail Submission setup that must be supported as well, SMTP+STARTTLS on port 587. It uses Explicit TLS: the client starts with a cleartext connection, then the server informs a TLS-encrypted \"upgraded\" connection may be established, and the client may eventually decide to establish it prior to the Submission. Basically it's an opportunistic, opt-in TLS upgrade of the connection between the client and the server, at the client's discretion, using a mechanism known as STARTTLS that both ends need to implement.</p> <p>In many implementations, the mail server doesn't enforce TLS encryption, for backwards compatibility. Clients are thus free to deny the TLS-upgrade proposal (or misled by a hacker about STARTTLS not being available), and the server accepts unencrypted (cleartext) mail exchange, which poses a confidentiality threat and, to some extent, spam issues. RFC 8314 (section 3.3) recommends for a mail server to support both Implicit and Explicit TLS for Submission, and to enforce TLS-encryption on ports 587 (Explicit TLS) and 465 (Implicit TLS). That's exactly <code>docker-mailserver</code>'s default configuration: abiding by RFC 8314, it enforces a strict (<code>encrypt</code>) STARTTLS policy, where a denied TLS upgrade terminates the connection thus (hopefully but at the client's discretion) preventing unencrypted (cleartext) Submission.</p> <ul> <li><code>docker-mailserver</code>'s default configuration enables and requires Explicit TLS (STARTTLS) on port 587 for Outbound Submission.</li> <li>It does not enable Implicit TLS Outbound Submission on port 465 by default.

One may relax that constraint through advanced custom configuration, for backwards compatibility.</li> </ul> <p>A final Outbound Submission setup exists and is akin SMTP+STARTTLS on port 587, but on port 25. That port has historically been reserved specifically for unencrypted (cleartext) mail exchange though, making STARTTLS a bit wrong to use.

Kubernetes provides multiple ways for doing that; each has downsides and complexity. The major problem with exposing <code>docker-mailserver</code> to outside world in Kubernetes is to preserve the real client IP. The real client IP is required by <code>docker-mailserver</code> for performing IP-based SPF checks and spam checks. If you do not require SPF checks for incoming mails, you may disable them in your Postfix configuration by dropping the line that states: <code>check_policy_service unix:private/policyd-spf</code>.</p> <p>The easiest approach was covered above, using <code>externalTrafficPolicy: Local</code>, which disables the service proxy, but makes the service local as well (which does not scale). This approach only works when you are given the correct (that is, a public and routable) IP address by a load balancer (like MetalLB). In this sense, the approach above is similar to the next example below. We want to provide you with a few alternatives too. But we also want to communicate the idea of another simple method: you could use a load-balancer without an external IP and DNAT the network traffic to the mail-server.

+<h2 id="preliminary-steps"><a class="toclink" href="#preliminary-steps">Preliminary Steps</a></h2>
+<p>Before you can get started with deploying your own mail server, there are some requirements to be met:</p>
+<ol>
+<li>You need to have a host that you can manage.</li>
+<li>You need to own a domain, and you need to able to manage DNS for this domain.</li>
+</ol>
+<h3 id="host-setup"><a class="toclink" href="#host-setup">Host Setup</a></h3>
+<p>There are a few requirements for a suitable host system:</p>
+<ol>
+<li>The host should have a static IP address; otherwise you will need to dynamically update DNS (undesirable due to DNS caching)</li>
+<li>The host should be able to send/receive on the <a href="../config/security/understanding-the-ports/#overview-of-email-ports">necessary ports for mail</a></li>
+<li>You should be able to set a <code>PTR</code> record for your host; security-hardened mail servers might otherwise reject your mail server as the IP address of your host does not resolve correctly/at all to the DNS name of your server.</li>
+</ol>
+<p>On the host, you should have a suitable container runtime (like <em>Docker</em> or <em>Podman</em>) installed. We assume <a href="https://docs.docker.com/compose/"><em>Docker Compose</em></a> is <a href="https://docs.docker.com/compose/install/">installed</a>.</p>

+<h3 id="minimal-dns-setup"><a class="toclink" href="#minimal-dns-setup">Minimal DNS Setup</a></h3>
+<p>The DNS setup is a big and essential part of the whole setup. There is a lot of confusion for newcomers and people starting out when setting up DNS. This section provides an example configuration and supplementary explanation.  We expect you to be at least a bit familiar with DNS, what it does and what the individual record types are.</p>
+<p>Now let's say you just bought <code>example.com</code> and you want to be able to send and receive e-mails for the address <code>test@example.com</code>. On the most basic level, you will need to</p>
+<ol>
+<li>set an <code>MX</code> record for your domain <code>example.com</code> - in our example, the MX record contains <code>mail.example.com</code></li>
+<li>set an <code>A</code> record that resolves the name of your mail server - in our example, the A record contains <code>11.22.33.44</code></li>
+<li>(in a best-case scenario) set a <code>PTR</code> record that resolves the IP of your mail server - in our example, the PTR contains <code>mail.example.com</code></li>
+</ol>
+<p>We will later dig into DKIM, DMARC &amp; SPF, but for now, these are the records that suffice in getting you up and running. Here is a short explanation of what the records do:</p>
+<ul>
+<li>The <strong>MX record</strong> tells everyone which (DNS) name is responsible for e-mails on your domain.
+    Because you want to keep the option of running another service on the domain name itself, you run your mail server on <code>mail.example.com</code>.<br />
+    This does not imply your e-mails will look like <code>test@mail.example.com</code>, the DNS name of your mail server is decoupled of the domain it serves e-mails for.<br />
+    In theory, you mail server could even serve e-mails for <code>test@some-other-domain.com</code>, if the MX record for <code>some-other-domain.com</code> points to <code>mail.example.com</code>.  </li>
+<li>The <strong>A record</strong> tells everyone which IP address the DNS name <code>mail.example.com</code> resolves to.</li>
+<li>The <strong>PTR record</strong> is the counterpart of the A record, telling everyone what name the IP address <code>11.22.33.44</code> resolves to.</li>
+</ul>
+<p>If you setup everything, it should roughly look like this:</p>
