There is Stalwart.

It is a kind of all in one thing with web GUI and JMAP support.

No idea so far whether it is any good, as I did not look at it more
closely.

And there is still Courier IMAP and Cyrus IMAP around. Never looked at
these more closely either. Courier can do both, IMAP and SMTP. Support for
each protocol is separately packaged.

Anyway, I have done my Dovecot 2.4 configuration, so I am going to stick
with Postfix, Dovecot and Rspamd for now.

Best,
