Actually, I think he did supply that and it showed imap and pop3 not
getting any auth information.

There are other log options to verbosely log auth and ssl information, and
that might help.

I frequently see the above log messages when the client and the server
get their security protocol (SSL/TLS) and ports crossed up (i.e. trying
IMAP/SSL on port 143 or trying IMAP/TLS on port 993).  Try fiddling
with TB's setting here and see if anything shakes loose.

You can also use openssl and simulate the server end and maybe that will
shed light on the situation:

 	(You'll have to read the man page yourself to find all the options)
 	openssl s_server -accept 993 ...
