Set up Exchange to receive email for multiple domains

Follow these steps to configure Windows Small Business Server (SBS) 2003 and Exchange Server to receive email for multiple domains.

I am using Windows Small Business Server (SBS) 2003 with Exchange Server. I am not able to use multiple email IDs for different domains. I tried using suggestions from Microsoft for configuring Exchange Server to receive email for multiple domains, but it is still not working. Can you help?
Your Exchange server can definitely handle email for multiple domains. Here are the basic steps that you need to take:


  1. Configure your default Recipient Policy for the secondary domain(s). For example, if the primary domain is and a secondary domain is, then modify the policy by adding a second SMTP address in the format Click the OK button.

  3. When you see the screen that lists your SMTP domains, make sure that the checkbox next to the new domain is checked. Click the OK button.

  5. Accept the policy's prompt to apply the change to all user accounts/addresses if you want to do so, or manually add a new address for to any user account that should receive email for this domain.
