Using the dict quota with dovecot-1.0.rc21, quota reporting was incorrect. It wasn't just that the stored quota was different than the disk usage, but also that each time the quota was checked, it was greater than before, even if no mail was received. I tested this by using telnet to log into an imap account, and issuing multiple "getquotaroot inbox" commands.

I have changed to just using maildir quotas, and everything seems correct now. Thanks to dovecot's flexible authentication methods, I'll be able to set an individual account to use the dict quota backend for testing.
