Production-ready fullstack but simple mail server (SMTP, IMAP, LDAP, Antispam, Antivirus, etc.) running inside a container.
https://docker-mailserver.github.io/docker-mailserver/latest/
Generate systemd is deprecated and Quadlets are now used. I have spent some time getting Quadlet to work, so I added some findings to the documentation. It is my first time contributing to documentation, so excuse my English if it comes across a bit rambly. I have only added information, and have not removed any. However, generate-systemd is now deprecated and slirp4netns is out in favour of pasta. Pasta in particular is a lot easier to configure, but is still complicated to include into a docker-compose, which I do not use anymore. Using podlet you can also translate a docker-compose to a Quadlet. Quadlets themselves behave a lot like individual compose files, but are managed by systemd. |
