Hello.  We just upgraded one of our servers from RH 3.0.3 (IA32) to SL 
4.3 (x86_64 -- Opteron).

We're having serious problems trying to check mail on the new system. 
Local clients, such as mutt or pine, work just fine.  But checking for 
mail via IMAP from, say, Thunderbird or Squirrel Mail, always fails with 
some variant of "Mailbox does not exist" or "Invalid mailbox name" message.

We don't see any interesting error messages in the log files that 
correspond to the IMAP failures.

The system in question is an NIS and NFS server for client systems in a 
small classroom, by the way.

I notice that the IMAP server in SL 4.3 now runs as a separate daemon. 
I believe it was started out of xinetd in RH 3.  Perhaps I've simply 
overlooked some configuration setting for the new daemon?

I'd appreciate any help you can provide.  Thanks.

					- Mike
