[Dovecot] Dovecot imap with Postfix and using Thunderbird as client

[Shawn Needham]

Hi,

I was wondering if anyone knew of the mysterious fix to this problem that 
Curtis describes in his followup:
"I vaguely remember something like this, but I don't recall the fix"

I recently installed dovecot on a server running RHEL4-AS-U2 and have updated 
to RHEL latest dovecot package, dovecot-0.99.11-2.EL4.1.

Seeing as this is close to the version Curtis is running (dovecot-0.99.14) I 
was wondering if anyone had some insights.

There seems to be a Thunderbird specific problem when trying to retrieve 
messages from the server. Other imap clients (Mac OSX Mail, squirrelmail, etc) 
don't experience this problem, however Thunderbird 1.5.0.5 experiences it on 
Linux, Mac OSX and Windows boxes.

In thunderbird, new messages don't reliably appear and the retrieval button 
doesn't work when new mail is present. Clicking on an email which isn't cached 
retrieves new ones as well as waiting around an hour to retrieve messages.

Thanks in advance for any insight you can provide.
