Here is a good illustration of what a ridiculous waste of resourses these
bounces are:
----------------------------------------------------------
Jan 11, 23:35:02 GMT - Spammer at [209.76.20.55] emails
<lanval(_at_)menta(_dot_)net>
pretending to be <assumptionsccoth(_at_)mail(_dot_)yellowhead(_dot_)com>.

----------------------------------------------------------
Jan 12, 09:31:30 GMT - <smtp04> forwards email to <smtp08>. Why the server
waited 10 hours to forward email addressed to an unknown recipient is
beyond me. I can't imagine that there could be that big a backlog.
