if you are talking about 1 user who has 2 email addresses you will need to create 2 separate mailboxes and grant the user the right to send as the other user.

I have an Exchange 2003 DC 2003 box with two domains being servered by the Exchange.<br />
The server is named A.com and these users are sending as B.com. When I go into AD users and computers to give one user the right to send email as another user It shows the email as user@A.com.<br />
Even though that user is setup with user@b.com email address.<br />
Since they are being given access to the a.com email when the delegated user tries to send from the b.com for the other user the receive an error message saying they do not have the right to send for that user.<br />
<br />
Any ideas on how to get around this
