Re: Deleting "ghost" mailboxes that don't correspond to filesystem directories

I don't know the Debian/Ubuntu "cyrus" helper script. I will therefor  
refer to the
"ctl_mboxlist -d" which probably gives the list of mailboxes with some  
additional information


first check "unixhierarchysep:" setting in your imapd.conf. The default value
has changed in cyrus-imapd 3.0. But even if the setting is "1" (on)  
the ctl_mboxlist output,
some log-entries and error-messages still use the "internal" format  
where the hierarchy
separator is "."

also if I remember correctly, in cyrus-imap 2.4 tombstone records  
where introduced to the mailboxlist.
An entry with " 16 (null) " indicates an "recently" deleted mailbox
So you can ignore those.

If "unixhierarchysep:" is on you have to use
# cyrus reconstruct user/[redacted]/Templates

The "Invalid mailbox name" can indicate that "mailbox" does not exist  
in the mailboxlist,
e.g. because it has already been deleted, or because of the wrong hierarchy
separator is used.
