Issue with pop3s abnormally terminating

[Wesley Craig]

Kinda looks like a port probe.  telnet to the pop3s port and then use  
the telnet escape key to quit the connection.  If you'd like to  
submit a patch to reduce the level of logging for these errors to  
something a little more sane (like DEBUG), I'm sure it would be  
accepted through Bugzilla.
