I am a little confused here.

I have been running 2.2.34 which I installed in /opt/dovecot2.2 I installed 2.3.0.1 to /opt/dovecot23

I then used config files from /opt/dovecot2.2/etc/dovecot to /opt/dovecot2.3/etc/dovecot and all I did was sed -i.BAK 's/dovecot2.2/dovecot2.3/g'. Dovecot started and was running file.

Next, I manually crafted config files for 2.3.0.1 based on the example config files provided which diff-ing those with what I had for 2.2.34. I doub't if I missed something crucial during the process.

1. I realized that I cannot start 2.3.0.1 when I enable submission, since my Exim MTA is already using that port. This persists even if I tell the submission protocol to use a different port than 587. I tested 2587, but it would appear that 587 is hard-coded!

2. I realize that "unix_listener auth-client" service ceased to exist!

3. *I realized that while 2.2.34 runs with default_pass_scheme = MD5-CRYPT, 2.3.0.1 would not run with it.*

4. I have run dovecot -n from my 2.2.x installation and 2.3.x installation and here is the diff from the two files.

I am confused why authentication is failing with dovecot-2.3.0.1 when it uses 2.3.x config files using MD5-CRYPT scheme while it is succeeding with dovecot-2.2.34 using the same. *Mar 07 22:30:22 auth: Info: sql(user.name@domain.name mailto:user.name@domain.name,192.168.55.97,<4CETl9dmscvAqDdh>): Requested DIGEST-MD5 scheme, but we have only MD5-CRYPT*

Maybe the problem is elsewhere??? I need a 3rd eye to help me.

For now

Maybe I am just suffering brainlock and need to debug auth further, but I have see a question about this auth issue already from another poster, and it's not been answered by anyone.

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.
