So you're using the procmail NiXspam code, I guess? You might somehow
translate your hash and IP lists into zonefiles and feed them into an
DNS server. Alternatively use the hashhackserver to get those hashes
(only those) into a MySQL database. Building zone files from that data
Apart from me and Heise I don't know of anyone doing that (i.e.
publishing spam hashes) - which I think is a pity but I'm propably
If you plan to offer such a service get in contact with me per PM (and
in German I guess)
