Anyone curious about the BRBL.


In September of 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 the public and can be used within reason. Barracuda Networks is currently making this service available free of charge and we hope to keep it that way. Barracuda Networks does require free registration to gain access to the DNSBL. If you would like to register, please click here.

Registration is simple and immediate. Please note that this service is provided free of charge, therefore Barracuda Networks reserves the right to refuse service to spammers, competitors and other parties at the company's discretion. This service is provided as is with no warranty of any kind. No Email Security Gateway is required to use the BRBL.
