FYI - while that kinda works, it is slightly skanky, and leaves the
mailboxes.db and the "backup copy of the ACL" in the mailbox header
out of sync.  It's also going to break in future when the content
of mailboxes.db changes.  It's also somewhat incompatible with
replication, murder, etc.

The correct way[tm] is to iterate over all the mailboxes and do a
"setacl" for each one you want to change, probably using an external
script that talks IMAP.
