AntiSpam options
The FortiGate unit’s antispam feature detects unsolicited commercial email by identifying spam email messages and spam transmissions from known or suspected spam servers.
This feature requires a FortiGuard subscription and a registered FortiGate unit. When the FortiGate unit receives an email message, it verifies with the FortiGuard server whether it is a valid email or a spam message. FortiGuard Antispam is one of the features designed to manage spam. FortiGuard is an antispam system from Fortinet that includes an IP address black list, a URL black list, and spam filtering tools. The FortiGuard Center accepts submission of spam email messages as well as well as reports of false positives.
Depending on how you configure the FortiGate unit, the FortiGate unit will either tag the message with text so you can easily identify the spam, or delete the message before it reaches the recipient.
The FortiGate unit also enables you to create your own spam filters using banned words and black/white lists.
