Blacklist Monitor

Welcome to the Intra2net Blacklist Monitor, tracking more than 40 blacklists.

Blacklists, also known as RBL, DNSBL or URIBL, help administrators to block messages from specific IP's which have a history of sending spam. They can be used by software like SpamAssassin to reject or flag unwanted messages. Most public blacklists have their own standards and criteria for listing spammers. Hence, results can vary greatly from one to the other.
