I am wondering or under what scenario would a DSN (bounce) agent keep

It was a legitimate bounce for a non-delivery address.� But it kept
several headers from the original message in the DSN message headers:

��� DKIM-Signature:
��� Organization:
��� X-Mailer:

What logic is there to this?

RFC 3462, chapter 2.

The report does contain the original message. I speak of the actual 
bounce message from the mailer-daemon contain a copy of above headers:

    DKIM-Signature: d=santronics.com; ....    <--- copy
    Organization: Santronics Software, Inc.   <--- copy
    X-Mailer: wcMail v6.3.453.4               <--- copy
    Date: Fri, 01 Oct 2010 09:18:26 -0400
    From: mailer-daemon(_at_)xxxxxxxxxx(_dot_)com
    To: return-address(_at_)santronics(_dot_)com
    Subject: DELIVERY FAILURE: .........

The rest of the DSN body message with the message/rfc822 report 
attachment containing the original message was fine.

Am I still missing something?
