Not the mail spool (/var/spool/imap?) but the metadata spool (/var/lib/imap?). There are multiple databases in the metadata spool, one of which is the mailbox database that lists the mailboxes, their ACLs, etc... These databases can be in a variety of formats: skiplist, berkley db, flat, etc... It is important to see if you have an DBERROR (berkley) or skiplist error messages in your log as that might relate to the problem.
