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 .
