piler-examples VS docker-mailserver

Mailpiler might be what you're looking for. I saw it a few times as recommendation here. The docker compose setup is on GitHub.

You find reasonable compose files here and here

Maybe not quite what you're looking for but still related: Mailpiler. See also this compose file.

There's Mailpiler (docker-compose.yml) for this exact use case.

I'm convinced that Mailpiler is what you're looking for. You can simply spin it up with Docker.

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
