We currently have a Sonicwall NSA 2600. We also have a Small Business Server 2011 running Exchange 2010. The Sonicwall has NAT and firewall configured to pass the mail to the server. That is working fine.
I have activated a 30 day trial of Sonicwall's Anti-Spam Service. During the initial configuration I received the following pop up error: "Mail Server Auto-Detect Failed. The system detects there are one or more NAT and/or Rule policies that use a service group of a service port range that includes SMTP and non-SMTPservice ports. The system could not enable the Anti-Spam service using the current configuration.
The user guide for enabling Anti-Spam lists a step where you identify the mail server. I am assuming I need to delete the current NAT and Firewall rules forwarding mail to the server and let the Anti-Spam setup configure them again. Am I correct?
Any help is appreciated.
