Now a new, free alternative to Spamhaus has arrived: the Barracuda Reputation Block List (BRBL), provided by well-known, open source-based Barracuda Networks. And Barracuda CEO Dean Drako says the company has no plans to charge for the service in the future. He says that BRBL (pronounced “barbell”) “does cost us a little bit of money to run, but we think that the goodwill, the reputation and the understanding that Barracuda is providing the service will do us well in the long run.”
