GRID Check

This feature helps to check the GRID Network IP Reputation - 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 SonicWall receives a connection from a known bad IP address, it responds with a 554 no smtpd here error and the SMTP session is rejected.

This feature is only available when the Essential Protection Service Suite or Comprehensive Anti-Spam Service is licensed on the firewall.

To perform a grid-check

3. Click Go.
