Some stats from one of our SA servers. After about two days we had:
9076 SURBL hits 5373 SC2 hits 4813 SC hits 1148 SC2 hits that did not also hit SC 588 SC hits that did not also hit SC2 3701 XS hits 1890 SC2 hits that did not hit XS 218 XS hits that did not hit SC2
So it looks like sc2 hit about 10% more messages than SC.
Of the other lists:
7779 JP 6781 OB 5798 WS 4691 AB 7 PH
This is without analysis of FPs.
Would be very interested to hear how these new lists test out SpamAssassin corpora, or any other corpora or mail servers for that matter.
