I may have a unique question for Experts Exchange as I did a search and could find nothing that addresses my problem.
I have a Sonicwall NSA 2400 running firmware 184.108.40.206 and I just purchased and activated the Sonicwall Anti-Spam license for it. When I attempt to enable the service in the admin page, I get the following error...
"Mail Server Auto-Detect Failed
The system detects there are one or more NAT and/or Rule policies that use a service group or a service port range that includes SMTP and non-SMTP service ports.The system could not enable the Anti-Spam service using the current configuration.
Please check and modify your NAT and/or Access Rule policies to separate SMTP service from non-SMTP services at Firewall > Access Rules and Network > NAT Policies. "
I have existing rules in place for my Exchange Server and apparently one or several of the rules is conflicting with what the Anti-Spam service wants to do. I have contacted Sonicwall Tech Support but have not received a response yet. I have also scoured through their documentation but get conflicting resolutions to this error. Some things say to delete all of your SMTP-related rules from the firewall and then enable the service, which will create the rules it needs on its own. Other things say to separate your SMTP ports and services from non-SMTP ports and services and then enable but I am not finding any ports and services in my SMTP rules that are non-SMTP related.
Has anyone seen this error before and what is the best resolution to overcome it?
