About

The InterServer DNS-based Blackhole List is a spam trap DNSBL. This list does not take spam reports from third-parties. All blocking is done based on email recieved to our multiple spam trap email addresses throughout our network. For additional information click here.

Updates 5/13/2008

Gmail, Hotmail, and Yahoo server's are whitelisted in this RBL. We feel this is the best method to use at this point in our automated system.
