Dictionaries can be used along with the various 

dictionary-match()

 message 

filter rules and with content filters. 

The message filter rule named 

dictionary-match(<

>)

 (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
