Open Sonicwall to new Webroot SAAS email spam/virus solution

We currently are running SBS2008 with Exchange. Our email routes through our Sonicwall router and then on to ExchangeDefender and beyond.
We are switching over to Webroot's equivilent shortly and I confused on what needs to be setup once the mail hits the firewall.

I was thrown into the task on short notice so my expertise is limited. I think I need to setup

1. Inbound access rule (wan to lan) letting Webroot talk to the SMPT service
2. Outbound access rule (lan to wan) letting SMTP talk to Webroot service
3. Create an address object for the Webroot IP addresses that might talk to us
4. Create an address group with the objects in it, then use the group in the access rules

On the Exchange console, I think I only need to create a new smarthost so outbound traffic routes to Webroot


Did I miss anything? Nothing like trying to do this on Friday afternoon!!!!

Thanks!

Hi

Exactly right

Get the list of server ip's from Webroot and create a group of addresses on the sonicwall

Next create a rule stating traffic from internal to external (trust/untrust) for MAIL (port 25) goes to the group you created above only to ensure all mail goes through the solution

Create a bi-directional rule to enable mail from the group above to come into your system, port 25 and to the exchange server IP

Change the SMTP smart host to what webroot state.
