This topic explains how to use the Exchange Management Console or the Exchange Management Shell to modify an existing Send connector for Microsoft Exchange Server 2007.

In Exchange 2007, you use Send connectors to create a connection to the Internet and to remote e-mail systems that require a specific configuration. For example, some remote e-mail systems may use a smart host or may require that you send e-mail messages that are larger than your standard Exchange organization limit.

To perform the following procedures, the account you use must be delegated the following:

  • Exchange Organization Administrator role

To perform the following procedures on a computer that has the Edge Transport server role installed, you must log on by using an account that is a member of the local Administrators group on that computer.

For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.

Do not perform this procedure on an Edge Transport server that is subscribed to the Exchange organization by using the Edge subscription process. Instead, modify the Send connector on the Hub Transport server. The change will be replicated to the Edge Transport server when synchronization next occurs.

Only a limited number of the total available Send connector settings can be modified by using the Exchange Management Console. To access all available Send connector settings, you must use the Set-SendConnector cmdlet in the Exchange Management Shell.

  1. Open the Exchange Management Console, and perform one of the following steps:

    • To modify an existing Send connector on an Edge Transport server, in the console tree, select Edge Transport.

    • To modify an existing Send connector on a Hub Transport server, expand Organization Configuration in the console tree, and select Hub Transport.

  2. In the work pane, click the Send Connectors tab, and select the Send connector to modify.

  3. Under the name of the Send connector in the action pane, click Properties to open the Properties page.

    • Click the General tab to modify the name of the connector, the protocol logging level, or the fully qualified domain name (FQDN) that is advertised in the Simple Mail Transfer Protocol (SMTP) EHLO verb.

      In Microsoft Exchange Server 2007 Service Pack 1 (SP1), you can also use the General tab to modify the maximum message size that is allowed on the connector.
    • Click the Address Space tab to add, remove, or modify the address spaces that are used by this connector. For more information about address spaces, see Send Connectors.

      In Exchange 2007 SP1, you can also use the Address Space tab to modify the scope of the connector. Scoped connectors can only be used by other Hub Transport servers that exist in the same Active Directory site. Non-scoped connectors can be used by all Hub Transport servers in the Exchange organization.
    • Click the Network tab to configure mail routing to use DNS, to use smart hosts, and to configure the smart host authentication methods.

    • Click the Source Server tab to modify the Hub Transport servers or Edge Subscriptions that are associated with this connector. The Source Server tab is only available on Hub Transport servers.

  4. After you modify a setting, click Apply to save your changes and remain in the Properties page, or click OK to save your changes and exit the Properties page.

Although you can configure non-SMTP address spaces on a Send connector on a Hub Transport server, the Send connector uses SMTP as the transport mechanism to send messages to other messaging servers. Foreign connectors on Hub Transport servers are used to send messages to local messaging servers, such as third-party fax gateway servers, which don't use SMTP as their primary transport mechanism. For more information, see Foreign Connectors.

You can use the Set-SendConnector cmdlet to modify all available settings for an existing Send connector. The Identity parameter specifies the Send connector that you want to modify. The Identity parameter can be the GUID or the name of the Send connector.

The values that you specify by using the Set-SendConnector cmdlet replace the existing values that are configured on the Send connector. To preserve any existing values in a multivalued parameter, you must specify the existing value and any new values that you want to add when you run the Set-SendConnector cmdlet.

The command in the following procedure is an example of how to use the Exchange Management Shell to make the following changes to settings on an existing Send connector named "Connection to":

  • Change the maximum message size that is allowed on the connector to 50 MB.

  • Add a new address space for the domain named that has an address space cost of 5. You want to preserve the existing address space for the domain named that has an address space cost of 1 and was already configured on the Send connector.

  • Run the following command:

    Set-SendConnector "Connection to" -AddressSpaces ";1",";5" -MaxMessageSize 50MB
