@tygrysinc the one rule I learned by a lot of IT guys: dont run your own E-Mail Server. It's just a complexity hell of toolchains and standards 

@blub standards wise - those are standards and work reasonably well (save for entities like gmail that usually show little respect for those standards);

There were sometimes issues with mail from independent servers being marked as spam, but there are certain features that can mitigate the issue.

As for tooling - getting lots of moving parts working together well could be tricky, but there are ready-made solutions that do away with all the hassle.
