The Barracuda Reputation Block List (BRBL) is based on the Barracuda Reputation System and operates collaboratively to fight spam. When email is received, the connection is automatically analyzed to determine if the connecting machine is either an open proxy or a node in a spam-generating botnet. If either is true, the IP address is immediately added to the Barracuda Reputation Block List (BRBL).
Most IP addresses are blacklisted as a result of directly sending spam or viruses to the Barracuda Reputation System's detectors. The Barracuda Reputation System detects spam by using honeypots, special addresses created to receive only spam and do not belong to any real user and through analysis of captive spyware protocol activity.
You can check if your IP is blacklisted on the Barracuda blacklist by signing up. You can request your removal from the black list by following the link below.
