Many organizations are obligated by legal, regulatory, or business process requirements to process, filter, modify, and store e-mail messages that are transferred to and from the organization and the Internet, in addition to internal communications between individuals in the organization. The Transport Policy and Compliance infrastructure of Microsoft Exchange Server 2007 provides a set of rules that govern how e-mail messages are stored and processed based on a set of requirements. The following important features help you comply with these legal, regulatory, and business process requirements more easily:

• Transport rules agents   There are two transport rules agents in Exchange 2007. The Transport Rules agent runs on Hub Transport servers and helps you meet regulatory and corporate policy requirements. The Edge Rules agent runs on the Edge Transport server and helps you protect your organization from unsolicited commercial e-mail, or spam, and viruses. For more information about the transport rules agents and specific scenarios where they might be used, see the following topics:

• Journaling agent   The Journaling agent helps you configure how Exchange enforces e-mail retention policies on messages that are sent or received by departments or individuals in your organization, to and from recipients outside your organization, or both.
