Organization Configuration > Hub Transport

Applies to: Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1

Use the Hub Transport node under Organization Configuration to view and maintain the features of the Hub Transport server role.

The Hub Transport server role is deployed inside your organization's Active Directory directory service. It handles all internal mail flow, applies organizational message routing policies, and is responsible for delivering messages to a recipient's mailbox.

You can use the following tabs to configure the Hub Transport server role:

• Remote Domains
  Use this tab to view and maintain the remote domains in your configuration.

  Remote domains let you control mail flow with more precision, specify message formatting and policy, and specify acceptable character sets. After you create a remote domain, you can specify more advance formatting, policy, and character set configurations for messages that you exchange with the remote domain.

• Accepted Domains
  Use this tab to view and maintain accepted domains in your configuration.

  An accepted domain is any Simple Mail Transfer Protocol (SMTP) namespace for which an Exchange organization sends and receives e-mail. Accepted domains include those domains for which the Exchange organization is authoritative. An Exchange organization is authoritative when it handles mail delivery for recipients in the accepted domain. Accepted domains also include domains for which the Exchange organization receives mail and then relays to an e-mail server that is outside the Active Directory forest for delivery to the recipient.

• E-mail Address Policies
  Use this tab to view and maintain the e-mail address policies in your configuration. E-mail address policies determine the default format for users' aliases.

• Transport Rules
  Use this tab to view and maintain the transport rules in your configuration. The transport rules that you configure on one Hub Transport server are applied through Active Directory to all other Hub Transport servers in the Exchange 2007 organization.

  The transport rules that you configure on an Edge Transport server are applied only to e-mail messages that pass through that specific Edge Transport server.

• Journaling
  Use this tab to view and maintain the journal rules in your configuration.

  The Journaling agent is a compliance-focused agent that you can configure to journal e-mail messages that are sent or received in the Exchange 2007 organization. A journal rule can be applied to all e-mail, or scoped to apply to just internal or external e-mail.

• Send Connectors
  Use this tab to view and maintain the Send connectors in your configuration. There are no Send connectors created by default.

  In Exchange 2007, Send connectors create a logical connection to remote mail systems.

• Edge Subscriptions
  Use this tab to manage the Edge Subscriptions that allow for replication of configuration data from Active Directory to the local Active Directory Application Mode (ADAM) instance on the Edge Transport server. If you are installing more than one Edge Transport server, each server requires a separate Edge Subscription file.

• Global Settings
  Use this tab to manage the following transport settings:

  • Message size limits

  • Transport dumpster settings

  • Internal Simple Mail Transfer Protocol (SMTP) servers that are exempt from Sender ID and connection filtering

  • Delivery Status Notification (DSN) messages for internal message senders that are copied to the Microsoft Exchange Recipient

  These settings apply to all Hub Transport servers in the Exchange organization.
