The Barracuda Reputation Block List is used by Barracuda's own email security products, and other mail servers can query it too. Removal is by request, and Barracuda ignores repeat requests, so it pays to get it right the first time.
Free, no signup. See if Barracuda, Spamhaus, SpamCop, or other major blacklists have you listed.
Examples: 203.0.113.42 or example.com

Barracuda names the usual causes: a virus-infected or misconfigured mail server, infected PCs or a botnet on your network, a dynamic IP a spammer used before you, bulk mail that doesn't follow CAN-SPAM, or an open wireless network.
Once the cause is fixed, submit the BRBL removal form with your IP, email address, phone number, and a short explanation of what you fixed. Barracuda says valid requests are typically processed within 12 hours. Requests without real information are ignored, and so are repeats.
A Barracuda listing can get your mail blocked at companies running Barracuda email security. Generator Labs checks your IPs against Barracuda and hundreds of other blacklists and alerts you by email, Slack, SMS, or webhook when a listing appears. Free for your first host.
Typically within 12 hours of a valid request.
Barracuda ignores repeat requests. Fix the cause, then submit once.
