Yes, I see that the read receipt messages have a MIME part with:

Content-Type: message/disposition-notification
...
Reporting-UA: user; Microsoft Office Outlook 11
Final-Recipient: rfc822;user at whatever.com
Original-Message-ID:
<!&!AAAAAAAAAAAYAAAAAAAAAO2OIs7f5opBps+a9k9wgkrCgAAAEAAAA==@whatever.com>
Disposition: manual-action/MDN-sent-manually; displayed

So the precise term would be MDN (ref: RFC 2298) not DSN (ref: RFC 1891, 1892,
1894).  My mistake on the subject.

Thanks for the clarification.
