What is SenderBase?

The SenderBase Reputation Service (SBRS) provides an accurate, flexible way for you to reject or throttle systems suspected to be transmitting spam based on the "reputation" of the connecting IP address associated with the remote host. The SBRS returns a score based on the probability that a message from a given source is spam, ranging from -10 (certain to be spam) through 0 to +10 (certain not to be spam). Although SBRS can be used as a stand-alone anti-spam solution, it is most effective when combined with a content-based anti-spam scanner, such as Cisco Anti-Spam.
