Hi,
Yes, this is possible.
While configuring the Mail Flow Policy, you can specify if the system will or will not scan the messages with AS (Anti-Spam) or AV (Anti-Virus). You can edit the Mail Flow Policy in the WebUI, at :
Mail Policies > HAT Overview
Select the Mail Flow Policy you want to change the configuration about AS, the go to the Scan settings and disable AS. Then Submit and Commit the changes. This approach woud be better applied if you create a new Sender Group and new Mail Flow Policy so you do not change the system's defaults for the existent Sender Groups and Mail Flow Policies.
I hope this helps.
