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.
