 This may not work the way you intend.  If the final leg of transmission is
with an SMTP connection, the error message is likely to be generated at the
penultimate site before the message has reached the destination site.

 Basically, the mailbox is usually verified in the RCPT exchange before the
message is transmitted.  If there is an error reported, the sending mailer
will report the 'unknown user'.  For all you know, the unknown user message
might have tripped a bug which prevented the mail from going thru.

 Better to use Return-Receipt-To:

 Best is to ask the real recipient to produce an acknowledgement manually.
