According to http://www.deadbeef.com/anti-spam/bl-spam-deadbeef-com/ : This blacklist is no longer actively maintained, if you have a mail server that is blocking emails based on this list, please stop. I never intended this to be used to block emails anyway, as I didn’t blacklist spammers, just IP addresses that had no working abuse contact email addresses.
Is the information on our site wrong or incomplete? You don't want us to monitor your blacklist? Or do you operate a similar blacklist? We would like to hear from you!
