Testing Content Dictionaries
The 
trace
 function can provide quick feedback on message filters that use the 
dictionary-match()
 rule. See 
Debugging Mail Flow Using Test Messages: 
Trace, page -446
 for more information. You can also use the 
quarantine()
 action 
to test filters, as in the 
quarantine_codenames
 filter example above.
DLP Dictionaries
DLP dictionaries are groups of words or phrases that work in conjunction with the 
RSA DLP scanning feature on the appliance and are available to custom DLP 
policies. Use the DLP dictionaries to scan messages and message attachments for 
the words and phrases included in the dictionary in order to take appropriate 
action in accordance with your corporate policies. AsyncOS comes with a set of 
predefined dictionaries from RSA Security Inc., but you can create custom DLP 
dictionaries.
You can also create your own dictionary as a text file on your local machine and 
import it onto the appliance. Use line breaks for each term in the dictionary text 
file. Dictionary terms are case-sensitive and can contain non-ASCII characters.
