Do you have a write-up about this? I've been wanting to host my own almost entirely for the extra control over incoming mail and have been held back by the same worries. I'd like to see what a success story looks like.
I don't, sorry. The short story is that I use Docker Mailserver [0] with some customised config for SMTP relaying, spam filtering and Gmail fetching with spam filtering. I also have a Roundcube container.
Underneath though, it's a pretty standard Postfix + Dovecot setup and there are plenty of those around.
