Cisco AsyncOS 8.5 for Email User Guide
 
Chapter 9      Using Message Filters to Enforce Email Policies
  Message Filter Rules
The following filter blind carbon copies the administrator when the Cisco scans a message that contains 
any words within the dictionary named “secret_words.”
The following example sends the message to the Policy quarantine if the message body contains any 
words within the dictionary named “secret_words.” Unlike the 
only-body-contains
 condition, the 
body-dictionary-match
 condition does not require that all the content parts individually match the 
dictionary. The scores of each content part (taking into account multipart/alternative parts) are added 
together.
In the following filter, a subject that matches a term in the specified dictionary is quarantined:
This example matches an email address in the “to” header and blind copies an administrator:
copy_codenames:  
   if (dictionary-match ('secret_words')) {
       bcc('administrator@example.com');
       }
quarantine_data_loss_prevention:  
   if (body-dictionary-match ('secret_words')) 
       {
       quarantine('Policy');
       }
quarantine_policy_subject:  
    if (subject-dictionary-match ('gTest'))
        {
        quarantine('Policy');
        }
headerTest:
    if (header-dictionary-match ('competitorsList', 'to'))
        {
        bcc('administrator@example.com');
        }
