I just had a debugging session with folks at the computer center. It is a real mystery.

Manual pop3 connections work.
Moodle pop3 connections don't work*.
Moodle imap connections work.
Moodle pop3 connections to out-of-campus pop3 servers work.

All connections are from the same computer.

So, the way out of impass is to change all users to imap. I would still love to know why pop3 stopped to work suddenly.

*) By not working, I mean that the sysadmin of the mail server does not see the incoming connection and Moodle reports login failure. No errors are logged even at the highest debugging level except those reported earlier.
