I need to run my own email server for some of my domains, because the providers that I usually use don’t support them (they use Unicode characters, and not everyone supports that yet). I have a small VPS that I run a few Docker containers on, and I’m wanting to try and run an email server on it as well. What containers are good for a low-hassle email setup? I don’t need a mailbox webui (ex: round cube), but it would be nice to have a UI for management. I do need multi-domain support, however.
You’re gonna have a bad time if you have to email MSFT/GOOG. MSFT was worse in my experience. their DumbScreen tech was horrible. Even the tech couldn’t get my emails to not go to spam. Gave up in the end. The likes of MSFT and Google make it nigh on impossible for people to self host their own email.
Been running my own mailserve for last 20 years and never had big issues.
Do dkim dmark stuff and DNS records properly and you will be fine. Also don’t spam and beware of spam-related subnets, and you should not have issues.
