[Dovecot] Testing IMAP clients with Dovecot, problems with MacMail

[Stewart Dean]

I've been testing my user community's IMAP clients when I try to login 
and then transfer a big message from the inbox into a folder in an 
overquota folder directory.  I am using native filesystem quotaing in 
AIXV5.3 with UWIMAP and comparing my results with what I see with 
Dovecot 1.0.0. (My Dovecot built without any plugins or quota extensions)

Everything matches/works except for Mac Mail under SSL with Dovecot..

Mac Mail:
1) with UWIMAP, login and mailbox load goes OK, then the illegal 
overquota xfer fails (as it should) with a popup reading 'Message could 
not be moved', with (port 993) and without (port 143) SSL
2) with Dovecot,
1) login and mailbox load goes OK to port 10143, plain listen, and the 
illegal xfer correctly fails as it should with a popup messge under a 
plain connection, but
2) When the port number is set to the Dovecot ssl_listen port and the 
SSL box is checked, Mac Mail doesn't bring up the inbox and folders...it 
acts like it can't connect. 

Has anyone else seen this behavior, and is there a fix?  Mac Mail is 
also known as Mail.app.  I am testing it at 1.3.11 and 2.1.1.  In the 
July '05 archive, I found this:

Is there anything I can do to get MacMail to behave correctly?  Or will 
it clear up when I shut down UWIMAP and give Dovecot the default ports.  
A Bronx cheer for Mac Mail........

My thanks in advance, S.


Everything else I tested behaves...for anyone that's interested.......
================ Over Quota Xfer results ====================

Insecure Pine from Unix login shell: refused by both UWIMAP (cannot 
exceed user or group quota) and Dovecot (there's not enough disk space.) 
server apps.  It is presumed that this will be used from within an SSH 
session to secure the transmission.

Webmail (horde, insecure and secure) : refused by both UWIMAP (cannot 
exceed user or group quota) and Dovecot (there's not enough disk space.) 
server apps.

PC:
TBird 1.5, 2.0, Sea Monkey and Netscape 7.2: get a popup with both 
UWIMAP (cannot exceed user or group quota) and Dovecot (there's not 
enough disk space.) server apps, both secure and insecure

Mac:
Seamonkey: ditto, same as PC Sea Monkey
Mac Mail or Mail.app only works insecure, as per above
