You *DID* know that there's some legitimate mail that isn't an error report
that goes with a MAIL FROM:<>, right?

In particular, LSoft's Listserv product sends the "confirmation cookie" messages
for opt-in lists with MAIL FROM:<> specifically *BECAUSE* if it's mailing to
'fred(_at_)foobar(_dot_)com' to confirm that it's a valid address and an 
intended request,
the bounce will be dropped on the floor if in fact it's a bogus address.
