A professor recently posed an interesting question to me. He receives 
e-mail regularly from the National Academy of Sciences and when he 
finishes reading the message and deletes it, he is asked to send a return 
receipt. This process happens automatically. Pine also know the return 
address of the person who is supposed to recieve the return receipt. all 
he has to do is answer yes. Does anyone know how this happens? Also, how 
would one set up such a system so he can do the same for e-mail he sends. 
TIA.
