Use the Sender Reputation feature to enable or disable sender reputation functionality for the local computer and to access the sender reputation properties pages.

Sender reputation continuously monitors senders and their past Simple Mail Transfer Protocol (SMTP) interactions, such as the amount of spam and messages that are not spam that a sender has sent. Sender reputation relies on such data about the sender to determine what action, if any, to take on an inbound message. Sender reputation functionality is also known as "protocol analysis."
