osc VS docker-mailserver

https://openbuildservice.org/ is one way to produce distribution packages across a wide selection of distributions, if your source code is open.

As fair as I understand, OBS is indeed a suitable replacement for AUR right now.

OpenBuildService is better in every way, is fully opensource everywhere and can even generate packages for ubuntu better than launchpad appears to, and can even build entire distros. No special integrations are necessary, it can cost-effectively work with a highly paralellized number of virtual machines (iinm 100 or more on generic threadripper or epyc).

Suse's OBS is another option, and there are likely others...

Good idea, give it a try. I'd recommend Kubuntu or Mint with Cinnamon. I switched to KDE for KDE Connects' amazing smartphone (Android) integration, which i recommend srrongly to try. Switched to openSUSE Tumbleweed myself, best KDE implemention IMHO, rolling release and the software selection is great, whats missing from the repos can be installed via opi, a client for [0]. It is not that newbie friendly though, since SUSEs' focus is on the enterprise ie safety over ease of use.

Try it on openSUSE, the best KDE integration by far IMHO, since it is their standard DE since IDK/forever? Tumbleweed offers the newest packages, rolling like Arch, but with a huge test battery on OBS (https://openbuildservice.org/). Snapshots on upgrade make the thought of breakage (haven't had any) tolerable.

Disclaimer: very happy user

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
