It will protect a lot of your ham while blessing very little spam. So if you are ham oriented, not losing good email, this is a list that will work for you.We received 52 spam messages per day on the average in January which got a hit on RCVD_IN_HOSTKARMA_W. Luckily we only score it at -0.5 . Of these 52 spam messages, 3.6 messages per day would have been treated as ham had we used a rule score -5 and required_hits 5. Examining messages that were blocked but whitelisted by RCVD_IN_HOSTKARMA_W, I found four newsletters in the whole January (not per day), each sent to avg three of our recipients, which could potentially be worth saving. None of them were worth rescuing from a quarantine. In summary, score of -5 for RCVD_IN_HOSTKARMA_W is grossly overrated. Mark
Mark, I think you are missing the important point. This user is more interested in getting good emails than rejecting spam. It's a different value system than yours. You have to understand it in terms of getting ham rather than rejecting spam.
