A Revised Internet-Draft is available from the on-line Internet-Drafts 
directories. This draft is a work item of the Receipt Notifications for 
Internet Mail Working Group of the IETF.                                   

       Title     : An Extensible Message Format for 
                   Message Disposition Notifications

This memo defines a MIME content-type that may be used by a mail user agent
(UA) or electronic mail gateway to report the disposition of a message 
after it has been sucessfully delivered to a recipient.  This content-type 
is intended to be machine-processable.  Additional message headers are also
defined to permit Message Disposition Notifications (MDNs) to be requested 
by the sender of a message.  The purpose is to extend Internet Mail to 
support functionality often found in other messaging systems, such as X.400
and the proprietary "LAN-based" systems, and often referred to as "read 
receipts," "acknowledgements," or "receipt notifications."  The intention 
is to do this while respecting the privacy concerns that have often been 
expressed when such functions have been discussed in the past.     

Because many messages are sent between the Internet and other messaging 
systems (such as X.400 or the proprietary "LAN-based" systems), 
the MDN protocol is designed to be useful in a multi-protocol 
messaging environment.  To this end, the protocol described in this memo 
provides for the carriage of "foreign" addresses, in addition to those 
normally used in Internet mail.  Additional attributes may also be defined 
to support "tunneling" of foreign notifications through Internet mail.

Internet-Drafts are also available by mail.	
Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-ietf-receipt-mdn-01.txt".
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
For questions, please mail to Internet-Drafts@cnri.reston.va.us.

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
