At one point seems like I found a write up in the Dovecot docs about having Dovecot directly listen on port 25 using Opportunistic TLS along with port 587 authentication, so only Dovecot was required to handle incoming email.
Said another way, no requirement for Sendmail, or Postfix or EXIM.
Just straight up Dovecot.
If I'm remembering correctly, someone point me to the correct docs for this setup.
Thanks!

You can use Dovecot submission service for this, but it will require a backing MX/MTA server to work.

Perfect!
Exactly what I was trying to find.
Thanks!

Why is this such a problem? Dovecot and postfix work together really well. You *don't* want submission on port 25 unless you do authentication, etc. But port 25 is for just plain SMTP. Especially if this host is exposed on the internet, it's not a smart thing to do.

Dovecot does IMAP well. It's not a mail server.
Can you explain more of what you're trying to do here? And why you think this is a good idea?
Postfix isn't hard to setup and works really well.
