<p>You should add at least one <a href="../config/user-management/#aliases">alias</a>, the <a href="../config/environment/#postmaster_address"><em>postmaster alias</em></a>. This is a common convention, but not strictly required.</p>

<p>You can (<em>and you should</em>) generate DKIM keys. For more information:</p>
<ul>
<li>DKIM <a href="../config/best-practices/dkim/#enabling-dkim-signature">with OpenDKIM</a> (<em>enabled by default</em>)</li>
<li>DKIM <a href="../config/security/rspamd/#dkim-signing">with Rspamd</a> (<em>when using <code>ENABLE_RSPAMD=1</code></em>)</li>
</ul>
<p>When keys are generated, you can configure your DNS server by just pasting the content of <code>config/opendkim/keys/domain.tld/mail.txt</code> to <a href="https://mxtoolbox.com/dmarc/dkim/setup/how-to-setup-dkim">set up DKIM</a>. See the <a href="../config/best-practices/dkim/#configuration-using-a-web-interface">documentation</a> for more details.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>In case you're using LDAP, the setup looks a bit different as you do not add user accounts directly. Postfix doesn't know your domain(s) and you need to provide it when configuring DKIM:</p>
<div class="highlight"><pre><span></span><code>docker<span class="w"> </span><span class="nb">exec</span><span class="w"> </span>-ti<span class="w"> </span>&lt;CONTAINER<span class="w"> </span>NAME&gt;<span class="w"> </span>setup<span class="w"> </span>config<span class="w"> </span>dkim<span class="w"> </span>domain<span class="w"> </span><span class="s1">&#39;&lt;domain.tld&gt;[,&lt;domain2.tld&gt;]&#39;</span>
</code></pre></div>

<p>You will very likely want to configure your DNS with these TXT records: <a href="https://www.cloudflare.com/learning/email-security/dmarc-dkim-spf/">SPF, DKIM, and DMARC</a>.</p>
<p>The following illustrates what a (rather strict) set of records could look like:</p>
<div class="highlight"><pre><span></span><code><span class="gp">$ </span>dig<span class="w"> </span>@1.1.1.1<span class="w"> </span>+short<span class="w"> </span>TXT<span class="w"> </span>example.com
