 A Revised Internet-Draft is available from the on-line Internet-Drafts 

       Title     : Mail Ubiquitous Security Extensions (MUSE)

Secure electronic mail can provide authentication of the source of mail and
confidentiality for its contents.  These features are becoming increasingly
important as the Internet grows exponentially and email is increasingly 
used for critical, sensitive, and confidential communications.  In 
addition, authentication can make mail filtering more effective and 
ubiquitous encryption indirectly makes all mail more secure be defeating 
traffic analysis based on distinctions between encrypted and non-encrypted 
mail and defeating bulk searching through insecure mail. 

However, use of secure mail is not widespread due to the problems 
of key distribution and lack of migration to secure mail enabled 
user agents.  This draft proposes partial solutions to these 
two problems by using coarser grained identity to permit 
some authentication and confidentiality without user agent 
change, and secure DNS for key distribution.  These changes 
also support limited host and domain level mail security policies.

Internet-Drafts are also available by mail.     
Send a message to:  mailserv(_at_)ds(_dot_)internic(_dot_)net(_dot_) In the 
body type: 
     "FILE /internet-drafts/draft-eastlake-muse-02.txt".
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 Internet-Draft.
