Blacklists which do this quickly find themselves not
being used anymore, and disappear over time (or
become the maintainer's personal hobby-horse).
I get mildly annoyed when people talk about "RBLs" as if
they are somehow all the same. The difference between
SPEWS and the CBL is about like natural ice vs. Westvleteren
12.... There's no comparison, all they have in common
is being a dnsbl/alcoholic beverage.
Personally, I would recommend the spamhaus sbl-xbl
(a combined list of the sbl, the cbl, and two other
open proxy lists) as a good one which catches a lot
of spam with few if any false positives, and none
of the "spite listings" and "escalations/collateral
damage" which give RBLs a bad name.
