multiple email addresses

Open Exchange, go to the particular recipient, double click on the recipient, this brings up the Properties box, go to Email Addresses Tab, click on the New tab and give the recipient an additional SMTP address.

Double click on the persons mailbox. This brings up the Properties box for that mailbox. Click on the E-mail Addresses Tab, This will show the current SMTP and well as the any other address, most likely an X.400 address. Then Click on the NEW buttonand then click on Internet Address, Click OK, then type the new address (joenelson@exchange.com) Click Apply and then Click OK. You should now have more than one address for Joe the user.
Since you are only giving multiple SMTP examples above, if this answer doesn't cut the mustard again, I would need more information
Good Luck

The answer above should be all that's required, plus about 15 to 20 minutes to let it propagate if you have multiple servers. If it's not working, what happens when you try? I assume you get an NDR message - what does it say? One thing you could try to troubleshoot is select one of the new addresses and click "Set as Reply Address" at the bottom. Wait a few minutes, then send a test message from the mailbox in question to an external mailbox and see if it uses that as the address. If it does, then retry sending a message in to that address
