For those that don't know what this plugin does: It uses an algorithm
developed by Bert Ungerer of the German IT magazin iX (Heise Verlag)
to compute fuzzy checksums from (spam) emails and checks them against
those hashes I and Heise computed from our spam ( and serve via DNS).
In short, this puts it in the league of Pyzor, Razor and DCC. It's
certainly no 'German Wunderwaffe' against spam but I think it has its
merits.
Since 1 July, we have had about 10K matches on checksums, and about 16K
hits on the IP-list. I think it's quite a useful tool.
If you happen to have some significant spamtrap feed you might also be
interested to set up your own hash database to check your production
mails against.
Yes, that's what we've done too - do you know of anybody else doing
this? It might be interesting to share databases/experiences.

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
is easy.
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
partial here.
If you plan to offer such a service get in contact with me per PM (and
in German I guess)
