FortiGuard spam submission
Spam submission is a way you can inform the FortiGuard AntiSpam service of non-spam messages incorrectly marked as spam. When you enable this setting, the FortiGate unit adds a link to the end of every message marked as spam. You then select this link to inform the FortiGuard AntiSpam service when a message is incorrectly marked.
