Configuring Exchange to receive mail for multiple domains

SUMMARY
This article describes how to configure an Exchange-based computer to receive mail for multiple domains.
MORE INFORMATION
By default, you are not allowed to relay unsolicited commercial e-mail in Exchange. If mail for multiple domains is being accepted on an Exchange computer, then the Default Recipient Policy must contain all domains. To configure an Exchange computer to receive mail for multiple domains:
1.        Start Exchange System Manager.
2.        Click to expand the Recipients container.
3.        Click Recipient Policies.
4.        Open the properties of the appropriate policy that is displayed in the right pane.
5.        Click the E-Mail Addresses tab, and then add any additional Simple Mail Transfer Protocol (SMTP) addresses that you want the Exchange-based computer to host. For example, to add a new SMTP mail domain, follow these steps:
a.         Click New, click to select SMTP Address, and click OK.
b.         In the Address box, type the at sign (@) followed by the name of the SMTP domain.

For example, to accept mail for xxx.com, type the following in the Address box, and then click OK:
@xxx.com
6.        Your new address space is now listed on the E-Mail Address tab. To enable your new address space, click to select the check box next to the address that you created, and then click OK.
