Thanks!
A word of caution. When attempting to collect IP address based abuse information, spoofed BGP announcements MUST be tracked as well. This topic or even mention of ASNs was excluded in the "Guidelines for Management of DNS-Based Reputation Systems for Email" written by Yakov Shafranovich, Nick Nicholas, Matt Sergeant, and Chris Lewis and published by Nick Nicholas on the ASRG reflector. This paper ironically excluded the role of the provider.
We're not going to be using the data as a honey pot, so it won't affect anyone's reputation. This is really just for "real-world" load testing and evaluation of new techniques. Our customers get lots of mail, but we have to be -- how shall I say -- careful with it!
A cooperative effort by providers is likely the _only_ viable solution for dealing with this chronic problem. Targeted abuse is also unlikely to be detected from disposed MX domains, but will detect amateurs.
I agree whole-heartedly. What is particularly missing IMHO is a spoofed-BGP-route blacklist. Anyone making any progress on that sort of thing? Regards, Ken -- Ken Simpson, CEO MailChannels Corporation Reliable Email Delivery (tm) http://www.mailchannels.com
