Enterprise Vault provides the following filtering features:
This feature provides simple filtering of Exchange Server journaled messages. You set up a filter for the Exchange Journaling task that selects, by address, the messages to archive. Other messages are deleted.
This feature enables the Exchange Journaling task to mark selected messages, in order to reduce the scope of subsequent searches. This can be particularly useful where there is a high volume of journaled email and you want to be able to identify messages sent between particular groups of users.
This feature provides more sophisticated filtering for Exchange Server user and journal mailbox archiving, public folder archiving and Domino server journal archiving. You create rules that select messages by matching one or more attributes, such as email addresses, subject text, message direction or the value of certain message properties.
The rules also include instructions on how selected messages are to be processed. This can include assigning a particular retention category, storing in a specified archive, deleting attachments of a specified type or size and deleting or marking the message.
The registry settings in this section enable filtering and control filter behavior.
