Genuity used to do a lot of work with this type of service, they refered me to Paul Vixie for mediation when a site we hosted back when I was at AnaServe decided to spam the world and they blackholed us.
Also, Paul Vixie (www.vix.net, I think)has some links to services of this type originally geared towards SPAM, but I'm sure it has these types of capabilities.
The Mail Abuse Prevention System (MAPS) Realtime Blackhole List was the first widely-used service of this type, I think: http://www.mail-abuse.org It can be used via BGP or DNS. But it's only meant for use with spammers, and I don't know if Paul and co. have packaged it up for use by others. -- North Shore Technologies, Cleveland, OH http://NorthShoreTechnologies.net Steve Sobol, BOFH - President, Chief Website Architect and Janitor Pictures of two of my 'children': http://www.WrinkleDogs.com About Spamfighters: "We're not net nazis.
