At the ripe age of five and a half ORDB.org, is shutting down, reads the notice on the web site.
"It's been a case of a long goodbye as very little work has gone into maintaining ORDB for a while. Our volunteer staff has been pre-occupied with other aspects of their lives. In addition, the general consensus within the team is that open relay RBLs are no longer the most effective way of preventing spam from entering your network as spammers have changed tactics in recent years, as have the anti-spam community."
The website will "vanish" by December 31, 2006.
The ORDBers recommend a combination of greylisting and content-based analysis (such as the dspam project, bmf or Spam Assassin) to try to keep yourself spam free from now on. µ
