Using SonicWall Anti-Spam and Barracuda Cloud Service in tandem

KyleCKnapp

Is it possible/advisable to use the Anti-Spam service in a SonicWall firewall to act as a second filter for mail coming from another anti-spam service, such as Barracuda?

Hi @KyleCKnapp

Yes it is possible your design. you can put behind the sonicwall ES or afterward any other brand spam filter.

Inbound traffic schema is below.

Sender email ---> Sonicwall Email Security Appliance --> Baracuda ---> Customer Mail server ---> customer users

Outbound traffic schema is:

Customer users --> Customer Email Server --> Baracuda ---> Sonicwall ES Appliance---> Recipient users.
