As per other recent threads, the PBL has become so reliable that it is now considered 'safe' to use as an RBL blacklist check at the MTA level before coming into spamassassin. Just use 'zen.spamhaus.com' for your check instead of sbl or xbl. If you don't have RBL checking before you invoke spamassassin (but you really should) then you can just score the PBL rule 10 or more - Charles

I just checked many of my FPs that have RCVD_IN_PBL, and increasing the score there would sure help me too! Thanks for spotting that, Aaron. Best, Alex

boosting PBL score suggestions
Hi, We're noticing that much of the spam which makes it through our filter hits the spamhaus pbl rule. However, that rule by itself scores only 0.9. Since we quarantine spam through a web interface (maia), we're pretty tolerant of false positives. Do any of you folks have a suggestion about raising the RCVD_IN_PBL score? I was thinking of raising it as high as 2 or 3. Another thing I'm considering is a META rule that scores for PBL + BAYES_60, etc. I am generally reluctant to mess much with the default scoring -- but I'm always looking for a better setup.
