serious over quota problem

Cyrus IMAP uses a 32bit int to store quota in bytes internally, this causes 
problems with large quotas.  While the bug says 2GB, from what I saw in the 
code a while back it's an unsigned long which should max out at 4GB.

Can one of the developers clarify 2/4GB as the maximum?
