What it lists
The Barracuda Reputation Block List (BRBL) is built from data collected across Barracuda's installed base and honeypots. It is consulted by Barracuda gateways and many third-party MTAs.
Who gets listed
IPs that have triggered Barracuda's spam signatures, sent to spam traps, or shown bot-like SMTP behaviour.
Reputation impact
High. BRBL is one of the most-consulted commercial RBLs and routinely causes deferrals at Barracuda customers.
How to delist
Fix the underlying spam source, then submit a removal request via the Barracuda removal form. Delisting is usually processed within 12 hours when the issue is resolved.
