Auto-reply to email to include original text body

Hi experts!

I have an employee leaving on maternity leave.  While she is gone, I want to be able to set up a out of office reply (or via some other method) where when someone emails her, they receive a reply that she is out of office, the email of a contact within the company and an attachment containing their original email (or possible the original email in the body text as if it were a "live" reply.

For example:

Joe emails Mary with some text.  Mary's autoreply emails Joe and says "I am on maternity leave.  Please contact Mark@soandso.com" and the autoreply has the original text Joe typed in included so Joe doesn't have to retype the email or go look in his sent mail and forward the original message.

Hope that makes sense!  
Anyone have any ideas how to do this?

I have a single Exchange 2003 server and everyone uses Outlook 2002 or 2003.  

Thanks!!
