The following example will help you configure your exchange Server 2007, to accept multiple Authoritive domains. i.e. myfirstdomain.com and myseconddomain.com

• You are changing your SMTP domain name, but have to continue to accept e-mail for the old domain name for a while. For example, you can use this procedure in the following case:
  • You change your organization name from myfirstdomain.com to myseconddomain.com.
  • You want to use myseconddomain.com as your SMTP domain name instead of myfirstdomain.com.
  You may have to keep the previous domain name for several months in case customers send e-mail messages to the previous e-mail addresses. You can set the new e-mail address as the "reply to" address. This means that the new address will be the default e-mail address displayed on all e-mail messages sent by the recipient. You can set the old e-mail address as a secondary address. This will enable the recipient to continue to receive e-mail that is sent to the old e-mail address.

Here Go:

To use the Exchange Management Console to configure Exchange 2007 to accept e-mail for more than one authoritative domain

1. Configure the accepted domain entry by following these steps:

• Open the Exchange Management Console. Expand the Organization Configuration node, and then click Hub Transport. Click the Accepted Domains tab in the results pane.  
• In the action pane, click New Accepted Domain… The New Accepted Domain wizard appears.
• On the New Accepted Domain page, type a name to identify the accepted domain entry. In the Accepted Domain field, type the SMTP domain name. Select Authoritative Domain. E-mail is delivered to a recipient in this Exchange organization. Click New.
• On the Completion page, click Finish.

*Note: That you may want to configure an email policy so that you mailboxes are configured to have the new SMTP address added to their configuration.
