Given we're suggesting logging the msgid, from, to, mailboxname and uid of 
every message delivered, I don't see too much of a problem in logging the 
msgid, mailbox name and uid of every message expunged, it should be a pretty 
similar order of magnitude and would provide very useful tracking 
information.
