Banned word
Control spam by blocking email containing specific words or patterns. The FortiGate
unit searches for banned words in email messages. If a match is found, the
corresponding protection profile action is taken. If no match is found, the email is
passed to the recipient.
You can use Perl regular expressions or wildcards to add banned word patterns to the
list. See
“Using Perl regular expressions” on page 335 .
This section describes:
• Banned word list
• Banned word options
• Configuring the banned word list
Note: Perl regular expression patterns are case sensitive for Spam Filter banned words. To
make a word or phrase case insensitive, use the regular expression
/i
. For example,
/bad language/i
will block all instances of
bad language
regardless of case. Wildcard
patterns are not case sensitive.
