Barracuda Reputation Database

Barracuda Reputation is a database maintained by Barracuda Central and includes a list of IP addresses of known good senders as well as known spammers, or IP addresses with a "poor" reputation. This data is collected from spam traps and other systems throughout the Internet. The sending history associated with the IP addresses of all sending mail servers is analyzed to determine the likelihood of legitimate messages arriving from those addresses. Barracuda Central continuously updates Barracuda Reputation.
