Barracuda Reputation Block List (BRBL)
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 BRBL is open to public and can be used within reason.
