The SenderBase Reputation Service (http://www.senderbase.org) provides an accurate, flexible way for
users to reject or throttle suspected spam based on the connecting IP address of the remote host. The
SenderBase Reputation Service returns a score based on the probability that a message from a given
source is spam. The SenderBase Reputation Service is unique in that it provides a global view of email
message volume and organizes the data in a way that makes it easy to identify and group related sources
of email. Cisco strongly suggests that you enable SenderBase Reputation Filtering.
