Can you send 'doveconf -n' for the 2.3.0.1 instance?

Also. You cannot use hashed passwords with DIGEST-MD5. MD5-CRYPT is
hashed password scheme.

To change dovecot's submission service port, use

service submission-login {
   inet_listener {
      port = 2587
   }
}

"auth-client" cannot be missing, since you can specify arbitrary
listeners in dovecot, so
https://wiki.dovecot.org/HowTo/EximAndDovecotSASL is still quite valid.
