Starting in September 2008, Barracuda Networks introduced the Barracuda Reputation Block List (BRBL – pronounced “bahr-bel”) as a free DNSBL of IP addresses known to send spam. Barracuda Networks fights spam and created the BRBL to help stop the spread of spam.

The Barracuda Reputation Block List (BRBL) is based on the Barracuda Reputation System and operates collaboratively to fight spam. The BRBL provides a list of IP addresses which are sending spam. The Barracuda Reputation system uses automated collection methods to add and delete IP addresses from the BRBL.

The automated spam trap, collection and rating system automatically adds IP addresses to the list when spam is detected. Barracuda Networks does not manually add addresses to this IP list.
