Adding a keyword or phrase
If you only wish to check for single words or phrases, you do not need
to create a condition. In this case you can just add a keyword. Select
Add Keyword to do this. If you enter multiple words, then GFI
MailSecurity will search for that phrase. For example if you enter
Basketball sports, then GFI MailSecurity will check for the phrase
Basketball sports . Only this phrase would activate the rule, not only
the word basketball OR sports.
5. By default, only the message body of the mail will be checked. You
can have GFI MailSecurity open an attachment and check for
keywords in the attachment itself. To do this, click on Attachment
checking options . Enable Check these attachments , and specify the
extensions of the attachments you wish to content check using the
Add & remove buttons.
This option will cost processing time, since it is time intensive to
search for words through attachments. Its best to only do this for doc,
txt and rtf attachments and to quarantine other attachments.
6. After you have specified keywords and combinations to check for,
you can select a number of options:
Match whole words only:
Enabling this option allows you to ensure
that GFI MailSecurity will only block mails where the word you specify
is a whole word. For example, if you specify the word sport, an email
with the word sport will be blocked, but not an email with the word
Block PGP encrypted mails:
This option will block/quarantine
messages that are encrypted using PGP. This will allow you to
intercept messages trying to bypass the GFI MailSecurity content
You can import keywords & conditions using the
Import/Export function. To do this, create a text file and include each
condition or keyword on a separate line. Phrases should be enclosed
in . Condition operators should be written in capitals. Tip: Export a
sample file to see the exact format.
7. You can now proceed onto the next tab and specify words that you
wish to check for in the subject of the message.
