A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the S/MIME Mail Security Working Group of the IETF.

        Title           : Enhanced Security Services for S/MIME
        Author(s)       : P. Hoffman
        Filename        : draft-ietf-smime-ess-07.txt
        Pages           : 31
        Date            : 05-Aug-98
This document describes three optional security service extensions for
S/MIME. These services provide functionality that is similar to the Message
Security Protocol [MSP4], but are useful in many other environments,
particularly business and finance. The services are:
 - signed receipts
 - security labels
 - secure mailing lists
The services described here are extensions to S/MIME version 3 [SMIME3],
and some of them can also be added to S/MIME version 2 [SMIME2]. The
extensions described here will not cause an S/MIME version 3 recipient to
be unable to read messages from an S/MIME version 2 sender. However, some
of the extensions will cause messages created by an S/MIME version 3 sender
to be unreadable by an S/MIME version 2 recipient.
The format of the messages are described in ASN.1:1988 [ASN1-1988].

NOTE:   The mail server at 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.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
