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           : Compressed Data Content Type for S/MIME
        Author(s)       : P. Gutmann
        Filename        : draft-ietf-smime-compression-01.txt

The Cryptographic Message Syntax data format doesn't currently contain
any provisions for compressing data before processing it.  Compressing
data before transmission provides a number of advantages including the
elimination of data redundancy which could help an attacker, speeding
up processing by reducing the amount of data to be processed by later
steps such as signing or encryption, and reducing overall message size.
Although there have been proposals for adding compression at other
levels (for example at the MIME or SSL level) these don't address the
problem of compression of CMS content unless the compression is
supplied by an external means (for example by intermixing MIME and
CMS).  This document defines a format for using compressed data as a
CMS content type.

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.

implementation to automatically retrieve the ASCII version of the
