Banned word Antispam
To access protection profile Antispam options go to Firewall > Protection Profile,
edit or Create New, Spam Filtering.
Banned word
Control spam by blocking email messages containing specific words or patterns. If
enabled in the protection profile, the FortiGate unit searches for words or patterns
in email messages. If matches are found, values assigned to the words are
totalled. If a user-defined threshold value is exceeded, the message is marked as
spam. If no match is found, the email message is passed along to the next filter.
Use Perl regular expressions or wildcards to add banned word patterns to the list.
Viewing the antispam banned word list catalog
You can add multiple antispam banned word lists and then select the best
antispam banned word list for each protection profile. To view the antispam
banned word list catalog, go to AntiSpam > Banned Word. To view any individual
antispam banned word list, select the edit icon for the list you want to see.

Note: If virtual domains are enabled on the FortiGate unit, spam filtering features are
configured globally. To access these features, select Global Configuration on the main
menu.
Note: Perl regular expression patterns are case sensitive for antispam banned words. To
make a word or phrase case insensitive, use the regular expression /i. For example,

patterns are not case sensitive.
