One possible solution in Cyrus, is to have expunge_mode on delayed, and 
then set the /vendor/cmu/cyrus-imapd/expire to something very large. 
Or, to place the expire notation deeper in the tree, so it can be 
removed from individual mailboxes.  This is a little clunky, and  it 
would be nice if 'Administrative Hold' were a mailbox setting in Cyrus.
