OpenDomain.org Grants Anti-Spam Website Greylisting.org with Free Domain

In appreciation of his work promoting the anti-spam effort greylisting, the domain Greylisting.org (www.greylisting.org) was transferred to Bjarne Lundgren by OpenDomain.org(www.opendomain.org).

"We apreciate the efforts and promotion of anti-spam measures and the work done by Bjarne Lundgren on the site," said Ric Johnson of OpenDomain.org. "Because of this, we have decided to accommodate Bjarnes' wish and grant him full ownership of the domain name."

Greylisting was first envisioned by Evan Harris, who wrote a popular whitepaper on the subject. The method is based on the concept that most spam is sent by "dumb" and misbehaving mail transfer agents that do not resend failed message attempts.

It works by temporarily refusing incoming messages from unknown senders. Legitimate mail transfer agents resend the messages and on the second attempt are accepted and the sender "whitelisted."

The website Greylisting.org contains valuable information about greylisting in general, as well as links to other anti-spam resources such as various implementation examples.
