Content Dictionaries

You can use content dictionaries to scan messages against message or content filters in order to take

appropriate action in accordance with your corporate policies. You can create, delete, and view

dictionaries; add and delete entries from a dictionary; and import and export entire dictionaries. You can

also determine case sensitivity and word boundary detection for each dictionary. For example, 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.
