Using the reputation service

The email protection system can check an email sender’s IP address against the reputation service, which classifies email senders based on past behavior. With this function, the email system can block mail from known spam senders. The reputation service is enabled from the section Reputation Service Options on the page Settings > Inbound/Outbound > Connection Control.
