Postal VS docker-mailserver

It looks like I'm not the only person who has faced this. apache-based images require buster, for instance, and some docker images that rely on Ruby face issues too (for example, I decided to try setting up Postal but it looks like it's facing the same issues).

A great self-hosted pairing might be Postal https://github.com/postalserver/postal

Previously I’ve used Postal, which is not simple but okay. Can I do better? Isn’t why I’m writing this?!

This is postal: https://github.com/postalserver/postal

Try Postal.

https://github.com/postalserver/postal is my go to favorite.

I can recommend Docker mailserver (it also works with Podman). It is already pretty lightweight but you can even make it lighter and it has an active community as well as regular updates.

Use https://github.com/docker-mailserver/docker-mailserver or mailcow . They both provide reasonable default setup for spam detection and even UI for adjusting settings.

" this docker based mail server looks pretty legit https://github.com/docker-mailserver/docker-mailserver "

Check https://github.com/docker-mailserver/docker-mailserver It has almost everything in a single docker image. Email is not the easiest to implement with container(s), but that project has managed it.

I set up docker-mailserver[0] Monday in ~6 hours, most of which were me trying to be fancy using podman instead of docker and dealing with SELinux. But then again I did choose it over mail-in-a-box for just that level of customization. Obviously I can't tell how reliable it will be in the long run yet, but since it's using the classic Postfix/Dovecot stack I expect it'll be pretty stable
