Even if you don't share my religous aversion to computers originating
mail about other mail, there is the problem that DSNs for spam are likely
to double-bounce into the local postmaster mailbox.  Then there is the
problem of some way for the filter program to tell the MTA that some
members of the addressee list should cause DSN's instead of get deliveries.
