IIRC he was complaining about junk DNS lookups to the RBL's original domain.
Correct. The conclusion of that thread can be found here: http://www.merit.edu/mail.archives/nanog/msg04555.html 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. 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. -Doug
