@david@daiwei.me I use Poste.io internally
Maddy at the edge – I’ve also hears good things about Mail-in-box, Mailu and Mox

@david@daiwei.me I use OpenBSD’s smtpd, which was super easy to set up. It gets a little bit more complicated these days because you also need a DKIM setup, so every outgoing mail goes from smtpd to dkimproxy and back to smtpd. And then dovecot for POP3/IMAP (has basically nothing to do with the other two).

I’m cheating a bit, though: I use config management on top, which means that all the UNIX users and mailboxes and directories are created by that. If you were to do that manually, it would be a huge pain.

Maybe I’ll write a blog post about this some day, just for fun. 🤔

JMAP? Never heard of it.

@david@daiwei.me I have never heard of JMAP before. Interesting.

We use Mailcow which is probably really overkill.
