you could create a list of confidential or profane words, and, using a filter rule to 
scan messages for words in the list, drop or archive messages containing matching 
words. And you can add a “weight” terms in a dictionary so that certain terms 
trigger a filter action more easily. 

Dictionaries can contain non-ASCII characters.

You can use data los prevention (DLP) dictionaries in custom DLP policies to scan 
outgoing messages for sensitive information. Similar to content dictionaries, you 
can create, delete, and view dictionaries; add and delete entries from a dictionary; 
and import and export entire dictionaries. Unlike content dictionaries, terms in 
DLP policies do not have a “weight.” AsyncOS comes with a set of predefined 
dictionaries from RSA Security Inc., but you can create custom DLP dictionaries.

Dictionary terms are case-sensitive and can contain non-ASCII characters. For 
more information on data loss prevention, see 

Text resources are text objects, such as disclaimers, notification templates, and 
anti-virus templates. You can create new objects for use in various components of 
AsyncOS. You can import and export text resources. 

Message disclaimer stamping allows you to add a disclaimer text resource to 
messages. For example, you could append a copyright statement, promotional 
message, or disclaimer to every message sent from within your enterprise.

AsyncOS provides two types of dictionaries: content and DLP dictionaries. For 
information on managing DLP dictionaries, see

Content dictionaries are groups of words or entries that work in conjunction with 
the Body Scanning feature on the appliance and are available to both content and 
message filters. Use the dictionaries you define to scan messages, message
