The following is a summary of responses I received regarding my problem 
with bounced mail not getting back to me, and what I have learned about 
network mail in general while trying to contact my friend at 
virginia.edu:  

Because of the large number of individual machines at the University of 
Virginia, a person has to add their name and the machine they wish to 
receive mail on to a database in order to receive mail sent to just 
their login @virginia.edu.  They can receive mail without registering if 
the sender knows what machine they are on and sends it to 
person@machine.virginia.edu.  I suspect that any organization having a 
large number of machines would be similar.

Some newer mailers will send a receipt or "successful delivery" notice 
to you if you include an extra header line similar to the following: 
Return-receipt-to: your-name@wherever-you-are.

Finally, sometimes a bounce notification does get back to you long after 
you sent the original message.  I finally got such notifications a week 
after I had sent my original letter and the subsequent test messages.
