Well, I was trying to find out if someone already has a DNS blacklist of
active spammer addresses/domains. In a few minutes of searching, I
haven't found such a beast. rfc-ignorant.org demonstrates that DNS
blacklists of domains are perfectly feasible, but they don't blacklist
spammers, they blacklist clueless/broken domains.
I'm not sure about the feasibility of blacklisting individual addresses
by DNS. Have to go read an RFC or two. For me, it's probably easier
just to maintain a file in one place and rsync it to the servers that
need it periodically.
