Configure a Dedicated Send Connector for a Specific Domain
Applies to: Exchange Server 2010 SP3
In some Microsoft Exchange Server 2010 environments, you may want to configure conditional SMTP forwarding so that all messages that are sent to a specific domain are routed through a separate Send connector. To do this in Exchange 2010, create a dedicated Send connector, and specify a different recipient domain for each Send connector.
Use the Exchange Management Console to create a dedicated Send connector
Open the Exchange Management Console on a computer that has the Hub Transport server role.
In the console tree, expand Organization Configuration, select Hub Transport, and then click the Send Connectors tab in the work pane.
In the action pane, click New Send Connector.
Note
The New SMTP Send Connector wizard starts.
On the Introduction page, type a name for the connector in the Name field.
In the Select the intended use for this connector field, click Custom.
On the Address space page, click Add.
In the SMTP Address Space dialog box, specify the address to which you want to route the mail. To do this, enter the recipient’s domain name under Address space. to For example, enter contoso.com.
Note
If it’s applicable, click to select the Include all subdomains check box, click OK, and then click Next.
On the Network Settings page, select Route mail through the following smart hosts, and then click Add.
In the Add smart host dialog box, enter the FQDN of the smart host that you want to use to route mail to the recipient’s domain. For example, to send connector to route mail to the contoso.com domain, use the smart host for contoso.com.
Click OK.
On the “Configure smart host authentication settings” page, select the method that’s used to authenticate to the smart host. By default, no authentication is used. To configure the smart host authentication settings, click Change, and then specify one of the following options in the window that opens:
None Select this option if the smart host is configured to accept anonymous connections.
Basic Authentication Select this option if the smart host requires Basic authentication. Basic authentication requires that you provide a user name and password. We strongly recommend that you use an encrypted connection if you're using Basic authentication. This is because the user name and password are sent in clear text. Select the Basic Authentication over TLS check box to enable encryption on the connection. Also, if you specify more than one smart host for this Send connector, all the specified smart hosts must accept the same user name and password.
Exchange Server Authentication Select this option to authenticate to a smart host by using an Exchange authentication mechanism, such as TLS direct trust or TLS\Kerberos.
Externally Secured (for example, with IPsec) Select this option if the connection to the smart host is secured by external means, such as being physically secured over a private network or secured by using Internet Protocol security (IPsec).
Click Next.
On the Source Server page, select the Hub transport server that you are working on. To use a different Hub Transport server, click Add, and then select the Hub Transport servers that you want in the Select Hub Transport or Subscribed Edge Transport Server dialog box.
To create the Send connector, click New.
Repeat these steps for each new Send connector. Make sure that you specify a different recipient domain name on the “Address space” page for each dedicated Send connector for which you want to configure conditional forwarding.
