the proper spam it is?

RP_MATCHES_RCVD is a check that the message metadata is internally

positive score.
Giving this rule positive value would uselessly add score to correct mail,
but any negative score increases possibility of false negative.
I don't think this should have any score, imho __RP_MATCHES_RCVD for meta
rules is just enough. It can be T_ rule if anyone wants, imho.
I have set score of this rule to 0 because of those.
In fact, as spams usually exhibit internal *inconsistencies* due to
being largely forged, a message *not* hitting RP_MATCHES_RCVD may
actually be a better spam indicator - that's probably the reason that
it has a negative score.
not hitting is very common by any hosted domains.
