Brightmail Reputation Service
Provides comprehensive reputation tracking that enhances the power of Symantec Brightmail Anti-Spam. Brightmail manages three lists as part of the Brightmail Reputation Service. Each of these lists operates automatically and filters messages using the same technology as Brightmails other filters. The Brightmail Reputation Service includes the Open Proxy List, the Safe List and the Suspect List.
The Open Proxy List is a dynamic database containing IP addresses of identity-masking relays, including proxy servers with open or insecure ports. Because open proxy servers allow spammers to conceal their identities and off-load the cost of emailing to other parties, spammers will continually misuse a vulnerable server until it is brought offline or secured.
The Safe List is a list of IP addresses from which virtually no outgoing email is spam.
The Suspect List is a list of IP addresses from which virtually all of the outgoing email is spam.
