Did you reconstruct the mailbox?  If not, you should so that the 
cyrus.index file gets updated.

If this doesn't solve the problem, then you might want to try removing 
the cyrus.index file from a test mailbox and then reconstructing it. 
This should update the UIDVALIDITY value which will force your client to 
refetch messages, even if it has seen a given UID already.
