Mail-in-a-Box VS docker-mailserver

may i recommend https://mailinabox.email ?

I don't see why we are a long way away. At the sandstorm end, we need to get to the point, where all updates (of both sandstorm and the apps) on the user machine are automatic. Much like they are automatic on various OSes (mobile OSes in particular but also MacOS/Windows). This is not impossible if a single OS like Debian-testing is targeted.

Mailinabox [1] almost does it. They target Ubuntu stable, and upgrades are mostly silent. But they needed user intervention when Ubuntu had to be upgraded from 18.10 to 22.04, which was quite challenging.

If sandstorm can get there, then putting it into a RPi box is simple. What's difficult is helping the general public understand the importance of protecting their data, so such a product has a reasonable market.

If you have a better solution, for example a good provider who offer agency packages which allows many domains and there is no catch, for example very small disk space, then hit me right away. Otherwise, please share your experience with hosting your own mail service. I found https://mailinabox.email/ and https://www.iredmail.org/ for example, but never had any experience with neither of them.

mailinabox.email works great on a basic vps.

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.

https://github.com/docker-mailserver/docker-mailserver https://docker-mailserver.github.io/docker-mailserver/latest/ https://www.programonaut.com/how-to-host-a-mail-server-with-docker-for-free-step-by-step/

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
