There seems to be a consensus that SPF and DKIM passes aren't worth significant scores. So how is it that RP_MATCHES_RCVD, scores -1.2 when it just a circumstantial version of what SPF does explicitly.
For me it's hitting more spam that ham, and what's worse, it's mostly hitting low-scoring freemail spam. Is it just me that's seeing this, or is there maybe some kind of bias the test corpora?
