Yes, self-hosting my email server since 2 years without issues so far. I only send a handful of emails per month but haven’t stumbled into any issues of being blocked by any big provider, even the ones that are known to block small email servers here in Germany. I enjoy the flexibility of as many aliases and distribution groups as I want for the family and being able to configure the anti-spam-component the way it works best for us.
I run everything on a small VPS at a known provider and checked the IP against block lists. It was indeed listed on one but I never had issues and when checking again a few days ago it wasn’t listed on any list anymore.
First I tried the available all-in-one solutions but troubleshooting is hard if you don’t know each component.
So, I followed this guide but moved all components in their own docker containers instead of installing natively to be more failsafe regarding system upgrades:
I’m a long-term Linux user living mostly on the terminal, knowing quite a lot about the operating system. And sometimes I enjoy tinkering to get a game running even more than playing it. But in the end for some games it just doesn’t work. Of course it depends on the game and hardware and what not, but in the end if I can’t play all my games on Linux I have to bite the bullet and check for alternatives. And for me this statement is hard as hell.
I started with an old office PC as my first server. Later I switched to a laptop which consumed way less energy and performed well. That worked for years until I got into Raspberry Pis and clusters and lately replaced 2 Pis with SFF PCs because of higher demand on CPU and RAM.
Use whatever works for your needs and expand when it doesn't fit anymore. But the most important thing: Have fun!
