Detecting Anonymously Registered Domains

Posted by kdawson on Tuesday March 2, 2010 @06:51AM from the may-i-tell-them-who-is-calling dept.

Spamresource.com has up a piece describing a new service that could be useful in evaluating the reputation of sites you deal with — anonwhois.org returns information on domains registered anonymously. It provides a DNSBL-style service that "is not a blacklist and wasn't meant to be used for outright rejection of mail." Only 619,000 domains are listed so far, but more are added as they are queried, so the database will grow more complete. Anonwhois.org seems to be a sister site to Spam Eating Monkey.

Which of course means that in a year or two us mail administrators will start encountering mail servers that have been setup to reject mail based soley on them being on this blacklist.
