The message filter rule 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
