Fortinet FortiGate 4000 Benutzerhandbuch

When the FortiGate unit detects an email that contains a word or phrase in the banned 
word list, the FortiGate unit adds a tag to the subject line of the email and writes a 
message to the event log. Receivers can then use their mail client software to filter 
messages based on the subject tag.

You can add banned words to the list in many languages using Western, Simplified 
Chinese, Traditional Chinese, Japanese, or Korean character sets.

Go to Email Filter > Content Block.

Select New.

Type a banned word or phrase.
• If you type a single word (for example, banned), the FortiGate unit tags all IMAP 

and POP3 email that contains that word.

• If you type a phrase (for example, banned phrase), the FortiGate unit tags email 

that contains both words. When this phrase appears on the banned word list, the 
FortiGate unit inserts plus signs (+) in place of spaces (for example, 
banned+phrase).

• If you type a phrase in quotes (for example, “banned word”), the FortiGate unit 

tags all email in which the words are found together as a phrase.

Content filtering is not case-sensitive. You cannot include special characters in 
banned words.

Select the Language for the banned word or phrase.
You can choose Western, Chinese Simplified, Chinese Traditional, Japanese, or 
Korean.
Your computer and web browser must be configured to enter characters in the 
language that you select.

Select OK.
The word or phrase is added to the banned word list.

Note: Email Content Block must be selected in the content profile for IMAP or POP3 email 
containing banned words to be tagged.
