402 Chapter 7 • Managing the Edge Transport Server Manually Confi guring the Required Connectors We assume that most organizations will create an edge subscription for the Edge Transport servers they choose to deploy in their perimeter network (DMZ or screened subnet). Since the EdgeSync service will automatically create the connector necessary to get a mail fl ow established to and from the Internet and to and from the Hub Transport server in the Exchange organization, no additional post-tasks are necessary regarding connectors; they will be replicated from the Hub Transport server to the Edge Transport server. But if for some reason you choose not to use an EdgeSync subscription, you’ll need to create these connectors manually. The Edge Transport server will need four connectors: two receive connectors (one is created during the installation of the Edge Transport server) and two send connectors. Since the Edge Transport server is located in the perimeter network (the DMZ or screened subnet), we assume that you have installed two network adapters in the server so that you can bind one receive connector and one send connector to the internally confi gured network adapter and one receive connector and one send connector to the externally confi gured network adapter. To create and confi gure the required connectors, follow these steps: 1. Create a Send connector that is confi gured to send messages to the Internet. To do so, log on to the Edge Transport server, open the EMC, and click Edge Transport in the navigation tree. 2. Now select the Edge Transport server in the Result pane and then click the Send Connectors tab. 3. Click New Send Connector in the Action pane to launch the New Send Connector Wizard. 4. Give the new Send connector a name, such as Send Connector (To Internet), choose Custom in the Intended Usage drop-down menu, and click Next (see Figure 7.23). SOME INDEPENDENT ADVICE The EdgeSync service supports edge subscription with only one Active Directory forest, so if your organization consists of multiple forests and you want to replicate each with your Edge Transport server(s), you will fi rst need to synchronize the recipient addresses to one forest, which you then replicate with the edge transport server using the EdgeSync service. If you originally did a transition from Exchange Server 2000 or 2003, the postmaster SMTP address will most likely already be associated with the Administrator mailbox. If this is the case, you need to remove the SMTP address from this mailbox before you can associate it with another mailbox. Managing the Edge Transport Server • Chapter 7 403 Figure 7.23 The New SMTP Send Connector Wizard 5. Now set the address space to *, which means all domains, and click Next. 6. You now need to decide whether you want to route mail using domain name system (DNS) MX records or using a smart host. If you’re required to route mail through an SMTP gateway located at your ISP or perhaps in your perimeter network (the DMZ or screened subnet), select Smart Host and enter the IP address of the respective SMTP server. (If you choose to use a smart host, select None on the Smart host security settings page, which will appear when you click Next.) Otherwise, select to route it using DNS MX records. On this page you also have the option of using external DNS lookup settings on the server. If you have or will create external DNS servers, enable this option and click Next (see Figure 7.24). 404 Chapter 7 • Managing the Edge Transport Server TIP If you’re using a smart host, you can, of course, also enter the FQDN of the SMTP server, but we recommend that you enter the IP address to reduce the performance load on the Edge Transport server.

Okay, you have created the fi rst Send connectors; now let’s move quickly on to the second. Managing the Edge Transport Server • Chapter 7 405 8. Once again, click New Send Connector in the Action pane to launch the New Send Connector Wizard. 9. Call the new Send connector Send Connector (to internal hub transport server) or something similarly meaningful and then select Internal in the intended usage drop-down menu. Click Next. 10. On the Address Space page, enter the domains that you already have added under the accepted domains tab on the Hub Transport server and click Next (see Figure 7.25). Figure 7.25 The New SMTP Send Connector Address Space 406 Chapter 7 • Managing the Edge Transport Server 11. Now select to route mail using a smart host. Enter the IP address of your hub transport server and click Next. 12. On the Smart host security settings page, select None and click Next (see Figure 7.26).

The next thing to do is to change the settings for the Receive connector, which are created automatically when you install an Edge Transport server. You’ll need to perform these steps: . connector and one send connector to the internally confi gured network adapter and one receive connector and one send connector to the externally confi gured network adapter.
