I get a lot of spam that passes the RP_MATCHES_RCVD test; it wouldn't make it into my inbox otherwise. I see the scoring recently got bumped to -3.0, which makes false negatives even more likely.
I'm not expert enough in the nature of spam to really understand why this test is so strong, nor to feel confident in simply whacking a few points off it without knowing more. In the year or so that I've been running my own mail server, I don't think I've seen a *single* false positive (at least not one that I noticed), but get maybe an average of two spam mails into my inbox every day. I've beefed up the BAYES scores, and that helped, but haven't tweaked anything else. Can anyone tell me why it's scored so heavily? Would it be a bad idea to just drop it down to -1.5 or something? Thanks, Eric
