The Horde Imap Client handles this situation just fine.  In fact, IIRC  
I actually helped Timo fix some broken behavior when it came to this  
in Dovecot.

Although looking at the code, detection of whether server side sorting  
is available is a bit muddled.  Maybe my recent commit helps?   Best  
way of verifying is to sort a mailbox by From/To and look for a line  
like this in the IMAP logs (make sure mailbox is not cached):

(1300207276.2820) C: 3 UID SORT RETURN (ALL COUNT) (DISPLAYFROM) US-ASCII ALL
