- Under URI Scan Settings, define whether All email or Suspicious email should be submitted to the FortiSandbox unit.
- Set URI selection to a system-defined URI filter profile from the drop-down menu, or create and assign your own. URI filter profiles use various FortiGuard categories as a filter for catching suspicious email content.
