I changed the maxfds to 4096 and will try removing mailboxes once again. >From my previous attempt described above, I still have /var/spool/imap/x/user/x with all the folders from the account in the directory. There appears to be no other trace of the account. Is it safe to just rm the var/spool/imap/x/user/x directory contents? I have a replica using sync_client which shows no trace whatsoever of the account, so it seems a safe bet, yes? thanks S ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
