Routing Mail to Your SonicWALL Email Security Appliance

In order for your SonicWALL Email Security appliance to start filtering and monitoring mail, you must re-route mail traffic through your SonicWALL Email Security appliance. Mail traffic must pass from the Internet to the appliance, and then the appliance sends the good mail on to your mail server.

You have two choices to route mail traffic to your SonicWALL Email Security appliance instead of to your mail server:

•Change the MX record in your DNS server to resolve to the IP address of your SonicWALL Email Security appliance. You may have to work with your ISP to change this record.

•Create a rule in your firewall or router to route all port 25 (SMTP mail) traffic to your SonicWALL Email Security appliance. Refer to your firewall or router documentation for instructions on creating rules to route traffic.
