GRID Network

The GRID Connection Management with Sender IP Reputation feature is used by SonicWall Email Security and by the Anti-Spam service in SonicOS. GRID Network Sender IP Reputation is the reputation a particular IP address has with members of the SonicWall GRID Network. When this feature is enabled, email is not accepted from IP addresses with a bad reputation. When SonicOS does not accept a connection from a known bad IP address, mail from that IP address never reaches the email server.

GRID Network Sender IP Reputation checks the IP address of incoming connection requests against a series of lists and statistics to ensure that the connection has a probability of delivering valuable email. The lists are compiled using the collaborative intelligence of the SonicWall GRID Network. Known spammers are prevented from connecting to the firewall, and their junk email payloads never consume system resources on the targeted systems.
