Do you use anti-spam DNS blocklists? If so, you should probably go take a look at DnsblAccuracy082005 on the SpamAssassin wiki; I’ve collated the results from our recent mass-check rescoring runs for 3.1.0, to produce have up-to-date measurements of the accuracy and hit-rates for most of the big DNS blocklists.

We don’t have accurate figures for the new URIBL.COM lists, btw — only the rulesets that are distributed with SpamAssassin were measured.
