content filters.

Dictionary Match Filter Rule
The message filter rule named 
dictionary-match(<
dictionary_name
>)
 (and its counterparts) evaluates 
to true if the message body contains any of the regular expressions in the content dictionary named 
dictionary_name. If that dictionary does not exist, the rule evaluates to false.
Note that the 
dictionary-match()
 rule functions similarly to the
 body-contains()
 body scanning rule: 
it only scans the body and attachments of messages, and not the headers.
For scanning headers, you can use the appropriate 
*-dictionary-match()
-type rule (there are rules for 
specific headers, such as 
subject-dictionary-match()
 and a more generic rule, 
header-dictionary-match()
, in which you can specify any header including custom headers). See 
“Dictionary Rules” in the “Using Message Filters to Enforce Email Policies” chapter for more 
information about dictionary matching.
