Note that the "Return-Receipt-To:" header is non-standard, and its
implementation varies among Mail User Agents:

     1) Return a receipt message when the mail is placed in the mailbox.
     2) Return a receipt message when the mail is read by the recipient
             (but not when it is discarded).
     3) Ignore and never return a receipt message.

If you do not get a return receipt from someone, you cannot assume that
the recipient has not seen the mail message.

I have seen cases where someone posts to a list and wants a return
receipt.  Then each person who reads the mail sends a return receipt - 
not to the sender, but to the list.  I do not remember what mailing
list software was being used.  I am not a big fan of return receipts.
