How to get delisted from Barracuda (BRBL)

Reputation blocklist used by Barracuda appliances and services.

Fix the cause first

1. Identify and fix the sending problem before you file — the form asks for the reason, and an unfixed source will simply trigger the automated listing again.

Not officially documented, but listings are reputation-driven and automated — expect to be re-listed if the cause persists.

Then request removal

1. Submit the removal form with your IP, email address, phone number, and a real explanation of what caused the listing and what you fixed.
2. Barracuda states requests are typically investigated and processed within 12 hours when given a valid explanation.
3. Requests without valid information are ignored — and so are repeated submissions, so make the first one count.

Cost: Free. (EmailReg.org, a paid whitelist sometimes suggested alongside Barracuda, does not affect BRBL listings — don't pay for it expecting delisting.)

Before any delisting request — the fundamentals

• ·Find and clean the actual source: compromised accounts or machines, malware, insecure web forms, open relays or proxies (many "open relays" turn out to be infected machines).
• ·Set up SPF and DKIM on everything that sends, and publish DMARC.
• ·Give every sending IP meaningful, matching forward and reverse DNS (PTR).
• ·Make sure abuse@ and postmaster@ addresses exist, are monitored, and never bounce.
• ·Only then request delisting where the operator offers it — every major operator relists automatically (or keeps filtering) while the cause persists.
