What is Barracuda Reputation?
Barracuda Reputation Block List (BRBL) is maintained by Barracuda Networks, a security company providing email filtering products. Organizations using Barracuda appliances or cloud services automatically query BRBL during mail processing.
BRBL listings indicate spam behavior detected by Barracuda's network of sensors and customer reports. Listing criteria include spam trap hits, complaint patterns, and automated detection algorithms.
Barracuda provides a lookup and removal tool. Legitimate senders can request delisting after addressing underlying issues. BRBL is less globally impactful than Spamhaus but affects delivery to organizations using Barracuda products, which includes many enterprises.
