Transport rules in Microsoft Exchange Server 2007 let you apply messaging policies and antivirus and anti-spam restrictions to e-mail messages that flow into, out of, or through an Exchange 2007 organization. You can configure transport rules on computers that have the Hub Transport server role or Edge Transport server role installed.
Although transport rules can be configured both on Hub Transport servers and Edge Transport servers, the predicates and actions that are available on each server role and the scope of the transport rules are different. For more information about these differences and about predicates and actions, see Understanding How Transport Rules Are Applied in an Exchange 2007 Organization.
For more information about the Transport Rules agent and Edge Rules agent, see Overview of Transport Rules.

Transport messaging policies are enhanced by or are also available as a service from Microsoft Exchange Hosted Services. Exchange Hosted Services is a set of four distinct hosted services:
Hosted Filtering, which helps organizations protect themselves from e-mail-borne malware
Hosted Archive, which helps them satisfy retention requirements for compliance
Hosted Encryption, which helps them encrypt data to preserve confidentiality
Hosted Continuity, which helps them preserve access to e-mail during and after emergency situations
These services integrate with any on-premise Exchange servers that are managed in-house or Hosted Exchange e-mail services that are offered through service providers. For more information about Exchange Hosted Services, see Microsoft Exchange Hosted Services.
