You don't. You tell him to use MSN's smtp servers. It has become an accepted
practice that you use the smtp of your ISP to send email.

Or, if you really want to make it look like he's using your raq, create a
CNAME entry for MSN's smtp servers on your box and tell the customer to use
that.

The only other alternative would be to open your relay to every dialup IP
that MSN has, which could not be accomplished simply by adding www.msn.com
to your relay box.
