Exchange Server 2010 cannot send out SMTP messages to the Internet by default. To achieve
this you’ll need to create an SMTP connector, which is a connector between one or more
Hub Transport Server and the Internet. Since this information is stored in Active Directory,
all Hub Transport Servers in the organization know of its existence and know how to route
messages via the SMTP connector to the Internet.
To create an SMTP connector to the Internet, follow these steps:
1. Logon to the Exchange Server 2010 server using a domain administrator account, and
open the Exchange Management Console;
2. Expand “Microsoft Exchange On-Premises” and then expand the Organization
Configuration.
3. Click on the Hub Transport, and then click on the “Send Connectors” tab in the middle
pane;
4. In the Actions Pane click on “New Send Connector”;
5. On the Introduction page enter a friendly name, “Internet Connector” for example,
and in the “Select the intended use for this Send connector” drop-down box select the
Internet option. Click Next to continue;
6. On the Address Space page, click on the Add button to add an address space for the
Internet Connector. In the address field enter an asterisk *, leave the cost on default and
click OK. Click Next to continue;
7. On the Network settings page you can select if the Send Connector will use its own
network DNS settings to route E-mail to other organizations, or to use a smart host.
Change this according to your own environment and click Next to continue;
8. On the source server page you can choose multiple source servers for the Send
Connector. You can compare this to Bridgehead Servers in Exchange Server 2003. When
you enter multiple Hub Transport Servers, the Exchange organization will automatically
load balance the SMTP traffic between the Hub Transport Servers. Since we have only
one Hub Transport Server installed we can leave this as default. Click Next to continue;
9. Check the Configuration Summary, and if everything is ok click on New to create the
Send Connector;
10. On the Completion page click Finish.
You have now created a Send Connector that routes messages from the internal Exchange
Server 2010 organization to the Internet.
