Just as another note, it is possible to do this without modifying
sendmail, although the method can only be described as a kludge.
(Since sendmail refuses to distinguish between incoming mailers, the
situation is even kludgier than it would have to be.)  What you do is
have sendmail `deliver' everything to a program that does the routing,
then hands the message back to sendmail for *real* delivery.  You have
to pick some `unlikely' string to distinguish between first-time
addresses and routed addresses (`host.ROUTING-TRASH'? :-) ).
