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.
Seems really low. I run it on a docker LXC with Nextcloud and bunch of other stuff, on 8 cores of an ancient dual Xeon Dell. I never seem to have to deal with latency on it.
