Symantec Messaging Gateway features Brightmail Adaptive Reputation Management (Brightmail ARM). Brightmail ARM includes features designed to reduce unnecessary incoming email traffic, protect your network from attacks, and optimize the use of your processing resources. Brightmail ARM includes technologies that can reject or defer incoming connection attempts based solely on the incoming IP address.
You can reduce the cost of processing by managing connection load and distinguishing between connections from senders that are known to send spam and legitimate senders. The Connection Classification feature dynamically manages connection load based on the local reputation data that is collected automatically.
