I don't think we disagree.  My point-of-view is purely it's use in
my personal mail filters.  If using it blocks the wrong thing,
it's not accurate _for me_.

I like the idea of using RBL or Orbz to trigger a special filter though,
and might give that a try.

The problem here is that it's possible to have open relays on your
domain, and you don't have control over that machine. Should you be
blacklisted in that case? I don't know if Orbz would blacklist in that
case, but some people have. A company I worked for was blacklisted
because a customer's machine had an open relay. As I recall, it was
difficult for us to reverse the situation, and lawyers were involved.
