A New Internet-Draft is available from the on-line Internet-Drafts directories.


	Title		: Challenge / Response Interworking (CRI) Framework for 
                          Challenge / Response Email Systems
	Author(s)	: E. Dean, Y. Shafranovich
	Filename	: draft-irtf-asrg-cri-00.txt
	Pages		: 0

SMTP was designed simply to deliver email messages without
authenticating sources or senders of email messages. In an
affort to reduce spam on the Internet, Challenge/Response 
('C/R') email systems were developed to provide a method
for validating message origination for an intended recipient.
This document defines a Challenge / Response Interworking 
('CRI') protocol by proposing the use of SMTP extensions and 
MIME headers for interoperability of C/R systems. This
document also defines a set of guidelines for continued
use with existing non-CRI mail systems and clients.

Internet-Drafts can also be obtained by e-mail.

Send a message to:
	mailserv@ietf.org.
In the body type:
	"FILE /internet-drafts/draft-irtf-asrg-cri-00.txt".
	
NOTE:	The mail server at ietf.org 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.
