[comp.mail.misc] Bounce Notification Reliability

About how reliable is is the "nondelivery notification" on network mail, 
and about how long does it take?

I recently tried to contact a friend at the University of Virginia.  I 
sent the letter to my friend's id @virginia.edu.  He never received the 
mail, and I never got it back.  

As a test, I tried sending letters to the following:
xyz@bogus.edu
xyz66@virginia.edu

Now I assume these letters should have bounced rather quickly, but it 
has been four days and I havn't seen any trace of them.  Is this normal, 
or is it just the system I'm on (Portal)?  I know that in the past I 
have received mail responses to my Usenet postings (though I guess I 
have no way of knowing if I have received all or even the majority of 
the letters that were actually sent).

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.
