DNS standpoint: easy. Just add an MX record with a higher "distance" value. Servers looking to deliver mail to you will first try the lower "distance" record, which would be your exchange server. If it fails, they'd try the next higher MX, which could be your linux box. Software: again, easy, but depends much more on which smtp software you choose. For qmail, you'd just do a "echo mydomain.com >> /var/qmail/control/rcpthosts". I'm sure its also simple with other mailers. Another nice feature of qmail is that when your primary mail server is back up, you could ssh in to the linux box and "killall -ALRM qmail-send" and it will instantly retry to deliver the mail to your main server.
