The Received headers can be used now, although there isn't any lookup.
(I'm still getting around to the results from the other lookup...)

I think a message_length token would be more effective against this sort
of mail.  Or even something funky like the ratio of hapaxes to
non-hapaxes (or to message length).  I don't get enough of these (in
fact, I haven't got any fn's yet) to be able to test this, though.
