After you install the Microsoft Exchange Server 2007 Edge Transport server role, you must enable and configure the agents that provide the messaging features that you want to deploy. An agent is a managed software component that performs a task in response to an Exchange 2007 event.

Transport agents in Exchange 2007 perform tasks that support messaging policy and compliance and the Built-in Protection features that support anti-spam and antivirus prevention and management.

This topic provides information about the default agent configuration for a computer that has the Edge Transport server role installed.

Agent Configuration

All the transport agents that are listed in Table 1 are available on the Edge Transport server role. An agent must be installed and enabled for you to use the associated transport feature. Only the agents that provide the messaging features that are designed to be deployed in the perimeter network are installed by default. The agents that are not installed are designed for use inside the organization on a computer that has the Hub Transport server role installed. Table 1 shows the default configuration for agents on the Edge Transport server role.
