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,
- 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,
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
- 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
- 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).
- None Select this option if the smart host is configured to accept anonymous connections.
- 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.
