[Dovecot] Expunge -A cannot find users

Hi List,

If I use doveadm expunge in this format expunge will delete the email

doveadm expunge -u test@planetseafood.com mailbox Archive ON '8-Nov-2010'

But in this format doveadm expunge -A mailbox Archive ON '8-Nov-2010', it will list all the users in the database and display the following and no messages are expunged.

doveadm(test@planetseafood.com@planetseafood.com): Info: User no longer exists, skipping.

The iterate_query = SELECT username AS username, domain FROM mailbox which is correct for the DB layout.

I am not using the expire plugin. Is this a permissions issue?

Thanks Kilburn
