[Dovecot] Problem authenticating iPod Touch

[Mark Leisher]

Given the (slightly edited) config info below, iPod Touch users are 
unable to connect, leaving the following message in the log file:

dovecot: Jul 23 10:00:40 Info: imap-login: Disconnected (auth failed, 0 
attempts): rip=1.2.3.4, lip=5.6.7.8, TLS handshaking: Disconnected

Even with maximum logging on, no other error messages seem related to 
this problem.

Am I missing something simple I didn't catch in the list archives? Or is 
it more likely a problem on the iPod side? The iPods connect to our 
non-dovecot IMAP servers with no problem.
