That worries me. Granted, at most that will add 0.479 to a message (when
used with the default 3.1.1 scores), but to have your #1 *ham* rule be one
that's supposed to identify *spam* doesn't speak well for the rule. I like
RFCI; I feed it bogusmx or DSN-violating mail whenever I can. But, the abuse
and postmaster lists contain far too many *major* ISPs for them to be
reliable indicators of spam.
