Error with cyradm

[Delorme Guillaume]

Hi all,   I'm new in cyrus, and I make a mistake when I created some mailboxes...I create a mailboxe named "bfax" instead of "user.bfax". I already posted here about problems with that mailbox and I think that's why I have problems with it. i wanted to remove that, and I delete /var/spool/imap/bfax directory ... But I still see the mailbox in the list... And I can't delete it, because I can't setacl on it :   localhost.localdomain> setacl bfax cyrus c setaclmailbox: cyrus: c: System I/O error I know I should had delete it first with cyradm... Is there a solution?   ( escuse me for my english) Thanks for all
