Ah, I had actually been mostly just thinking about inbound SMTP features. It should of course support outbound SMTP as well, but I’m less familiar about what functionality would be useful for that.
Outbound is mostly the same as inbound, except requirement of authentication and TLS for the "submission" (587/tcp) and ssl wrapped "smtps" port 465/tcp.
Features we'd want:
- authentication
- per user rate limiting might be handled by Dovecot MTA instead of external program?
- spam filtering trough milter?
- virus filtering trough milter?
- Per user Geo-blocking would be great!
- Protection from password guessing ?
Plus it would be great if it could check if the authentication is still valid when re-using connection, ref missing feature in postfix:
