OpenDomain.org (www.OpenDomain.org) announced on December 27 that 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.
Ric Johnson of OpenDomain.org said that OpenDomain.org appreciates the efforts and promotion of anti-spam measures and the work done by Bjarne Lundgren on the site, and that because of this, OpenDomain.org has decided to accommodate Bjarne’s 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 www.greylisting.org contains valuable information about greylisting in general, as well as links to other anti-spam resources such as various implementation examples.
