  Using and Testing the Content Dictionaries Filter Rules
In the following example, a new message filter using the 
dictionary-match()
 rule is created to blind 
carbon copy the administrator when the appliance scans a message that contains any words within the 
dictionary named “secret_words” (created in the previous example). Note that because of the settings, 
only messages that contain the whole word “
codename
” matching the case exactly will evaluate to true 
for this filter. 
In this example, we send the message to the Policy quarantine:
