Unable to delete mailbox

[Jim Norton]

Hello folks:

 I did something stupid.  I am runing Cyrus Imap 2.2.0 Alpha.
 One day I decided it was time to remove a mailbox because a 
 user wanted a different email name.
 
 So I delete the name and password information from the sasl2 database
 and then when into the /var/spool/imap/user and deleted the users
 directory.
 
 Now when I telnet to my imap port and log in as the administrator and
 try to do a " . delete user.mailboxname " I get an error:
 
 . NO System I/O Error
 
 When people send email to this user now,  Postfix just fallsback to delivering
 it to Cyrus where it goes into a black hole.  Problem is that the sender
 doesn't get a bounce email back.
 
 So anybody know how I can go about getting Cyrus to forget about that mailboxname?
 
 Thanks,
 Jim
