Cyrus backups and deleted (users, mailboxes)

You're right, the DELETED mailboxes do turn up in user backups 
automatically, so I think those renames are occurring as expected:

# /usr/lib/cyrus/bin/cyr_backup -f 
cyrus-backup/partitions/default/d/debbiep\@polyfoam.com.au_* list 
mailboxes | grep DELETED
r7vyz5wuyw3mfswj0xntumv2  1970-01-01 10:00:00 
polyfoam.com.au!DELETED.user.debbiep.Trash.Test.5D8B4FED
[...]

There are some DELETED entries in the %SHARED backup too, so I _think_ 
that renames are working there too, but I don't have enough data yet to 
know.  I'll go back and check when some more shared folder subfolders 
have been deleted.

It may not be a problem that the DELETED mailboxes aren't getting 
enumerated in XBACKUP.  By definition, a deleted mailbox will have no 
further transactions on it, so there shouldn't be any need for it to be 
transmitted during XBACKUP.  The only unknown at this stage is what 
happens after the deleted mailboxes hit their expiry age: will they 
vanish from the backup during compaction or will they need to be removed 
manually?  My server isn't old enough for me to tell.

Hurrah, I think.

Sincere thanks for the info so far.
