If you are looking for real numbers, this should be helpful for you: Blacklists Compared - weekly reports of DNS blacklists lookups http://www.sdsc.edu/~jeff/spam/cbc.html Blacklist Monitor - accuracy and inaccuracy rates of various blacklists http://www.intra2net.com/en/support/antispam/ Please pay attention that some blacklists do only list IP addresses for hours. When running the mass check you need realtime data to get reliable results. -- Bjoern Sikora
