This came up in the "Spam email many have RCVD_IN_DNSWL_MED" thread. DNSWL.org made an announcement about it with more details. Basically, free use only allows 100,000 queries per organization per day. Go over that enough, and you may get "RCVD_IN_DNSWL_HI" hitting all your email. If you're handling more than 100,000 emails a day, and don't want to pay for dnswl.org data, add to your spamassassin config: score RCVD_IN_DNSWL_HI 0 score RCVD_IN_DNSWL_MED 0 score RCVD_IN_DNSWL_LOW 0 score RCVD_IN_DNSWL_NONE 0 Disclaimer: I'm a dnswl.org admin. More discussion of network test free usage limits here: http://www.spamtips.org/2011/01/usage-limits-of-spamassassin-network.html Yes, it would still be nice if spamassassin had an option to just disable all of these. Maybe just commented out options in a config file?
