Well, yeah...but not impossible.  Fortunately, the spam engine cannot
control the Received: header added by the "another mail server".  I
have toyed with the idea of hacking sendmail so that if it sees a
summarily bounces the letter.  (Obviously, the list of what trips it
should be configurable somewhere.)  It seems to me this wouldn't lose
much desirable mail; anyone whose only mail access is through a spam
engine deserves to lose anyway. :-)

However, it would mean source hacks to some part of the mail system, to
sendmail in my case.  I'm not afraid to dive into sendmail, but it
really does seem like an ugly layering violation.  Dunno what else to
do, though.
