8. Back on the previous page, the Scoped send connector setting is important if your organization has Exchange servers installed in multiple Active Directory sites:
-If you don't select Scoped send connector, the connector is usable by all transport servers (Exchange 2013 or later Mailbox servers and Exchange 2010 Hub Transport servers) in the entire Active Directory forest. This is the default value.
-If you select Scoped send connector, the connector is only usable by other transport servers in the same Active Directory site.
When you're finished, click Next.
9. On the next page, in the Source server section, click Add +. In the Select a Server dialog box that appears, select one or more Mailbox servers that you want to use to send outbound mail to the smart host. If you have multiple Mailbox servers in your environment, select the ones that can route mail to the smart host. If you have only one Mailbox server, select that one. After you've selected at least one Mailbox server, click Add, click OK, and then click Finish.
After you create the Send connector, it appears in the Send connector list.
From the Send connector list, you can turn the connector on or off.
