Activate Anti-Spam on a Sonicwall NSA-2600 and forward mail to local Exchange 2010 Server

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.

Mail will be received by the Sonicwall and it will then forward to the Exchange server. You don't need NAT in that scenario so delete the NAT rule and that should be it.

You don't need to configure NAT is what I was getting at. It is configured automatically.

Thanks A lot.

Does Junk Store need to be installed on a server?  I wanted to install on my desktop (windows 10 Pro).

You are welcome!

Yes, JunkStore needs to be installed on your Exchange server or another server but nonetheless a server. Antispam can create a Junk Store on your Exchange server. The Junk Store quarantines messages for end-user analysis & provides statistics. This is NOT something you install on each user's machine...it is centralized.

worked perfectly.  Note:  had to change setting on exchange server to allow it to receive anonymous emails.
