Hi!
For what it's worth I'm now ahead of Barracuda on Jeff Makey's blacklist comparison chart. Not a scientific comparison but it's about all there is to compare blacklists. Now only abuseat.org and spamhaus have me beat. (apews doesn't count because they blacklist everything)http://www.sdsc.edu/~jeff/spam/cbc.html
Beat you with what, false positives? :-) Indeed, it doesnt tell much about -quality- of a list. So its only maths. Bye, Raymond.
