You asked I-D.

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


	Title		: Message Store requirements for Internationalized Email
	Author(s)	: K. Hurtta
	Filename	: draft-hurtta-eai-messagestore-00.txt
	Pages		: 13
	Date		: 2007-3-22
	
   The Email Address Internationalization (EAI) is implemented by
   allowing UTF-8 characters in SMTP envelope and mail headers.
   UTF8SMTP extension of ESMTP takes care that mails with UTF-8
   characters in SMTP envelope and mail headers are not delivered to EAI
   non-compliant SMTP servers.  This document describes mechanism how to
   keep messages with UTF-8 characters on mail headers separated from
   EAI non-compliant Mail User Agents.  This document also describes
   general requirements for UTF8SMTP Message Store.

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

Send a message to:
	mailserv at ietf.org.
In the body type:
	"FILE /internet-drafts/draft-hurtta-eai-messagestore-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.
