Spam filter

Spam filter provides configuration access to the spam filtering options you enable when you create a firewall protection profile. While spam filters are configured for system-wide use, you can enable the filters on a per profile basis. Spam filter can be configured to manage unsolicited commercial email by detecting spam email messages and identifying spam transmissions from known or suspected spam servers.

Table 29 describes the spam filter settings and where to configure and access them. To access protection profile spam filter options go to Firewall > Protection Profile, edit or Create New, Spam Filtering. See “Protection profile options” on page 223.
