Is there a good email server that can be run through Docker? (lemmy.ca)

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: roundcube), but it would be nice to have a UI for management. I do need multi-domain support, however.

EDIT: For anyone wondering, I decided to go with Mailu. Stalwart didn't play will with internationalized domains (although it was the only server to support EAI/SMTPUTF8), and Mailcow would have been a bit more difficult for me to change to bind mounts and reconfigure Docker networking with.

So I've been setting up Stalwart (but I probably won't be using it), and I only had to unflag my emails as spam on Gmail and Outlook once; it even was able to send straight to the inbox of another Gmail account! I did have one email get quarantined by Outlook, but it was probably because the email and sender name didn't match enough.
