I have deleted mail folders and files from my cyrus mail directory using "rm", but obvioulsy the mailboxes of these files are still in the Cyrus database, that is mailboxes.db. I have tried to correct this problem by dumping mailboxes.db into a text file (using ctl_mboxlist), editing the text file, and then reconstructing mailboxes.db. However, I am getting the error message "fatal error: can't read mailboxes file". Tried everything that comes to mind or read mailboxes.db, but without success. Please help.
