Just FYI, I had dovecot-core, dovecot-imapd, and dovecot-pop3d installed on the system.

So for now I am back on 2.2, but was willing to give 2.3 a run if I can get it going.   Any ideas as to what to look at to get this working, would be great.   As stated above, this is Ubuntu Server 16.04.03, and I am also running Postfix and amavis-new, but don't think they should really impact me using dovecot for email over POP3 or IMAP..

Noel, we have actually tried to make the packages compatible with distros so that the upgrade would work. In general I agree with you, but in this case we did actually take the extra effort to see that they would be reasonably compatible with debian/ubuntu/centos packages.

That said, the upgrade is a major version change, so things might be different. Expecting that things "Just Work" is bit too much.

https://wiki2.dovecot.org/Upgrading/2.3 should help figuring out what needs to be checked.
