Hi Dave,

This has come on this list before, check the archives for March 2010.
Thread was called:
 "Nested "INBOX" folders - hard to delete"

>From my quick read, it might be possible to do it with "cyradm", but you need 
to have "delayed expunge" turned off as, I believe, 2.3.x has/had a bug you 
might encounter otherwise.
