Hi.  This draft is an update on the SMTP approach to mailbox 
internationalization.

Three things:

	* I am copying the SMTP list on this because everything
	is getting connected to everything else, as my on-list
	discussion with Nathaniel about the "trace fields in the
	envelope" proposal illustrates.  Please, to preserve
	everyone's sanity, do not start parallel discussions or
	cross-post -- this one is clearly an IMAA issue, at
	least for historical reasons.
	
	* There is one more proposal I-D coming in this series.
	As a one-line summary, it outlines ("specifies" would be
	too strong at this stage, but that is the intent) the
	encapsulation model that this draft suggests for
	downgrading.
	
	* Very high-level summary of changes from the -01
	version: I have become convinced that, if we are going
	to have an internationalized structure for email --not
	merely a collection of kludges and workarounds-- we are
	going to need to make some rather basic changes.  They
	include SMTP extensions for i18n addresses and alternate
	addresses and UTF-8 headers as well as UTF-8 headers, in
	some form, themselves.  I've picked up on Paul's UTF-8
	header proposal because it seems sensible and nothing
	else is on the table, but the proposal announced below
	eliminates the need for alternate address headers and
	all of the mucking around in the message payload by MTAs
	they imply.   And I'm convinced that we should have
	_one_ header to cover this rather than a collection.
	I.e., the model is that one is internationalized or not,
	rather than one in which internationalization is done
	piecemeal and incrementally, with all of the profiling,
	multiplicative cases, and long-term cruft that would
	imply.

Please do not react to what you think is in this proposal 
without reading it or, especially based only on what you think 
it is about from reading the above.   That is a waste of your 
time and that of everyone on the list, as previous rounds of 
such discussions amply demonstrate.

best,
    john

Internationalization of electronic mail addresses is, if
anything, more important than the already-completed effort for
domain names. In most of the contexts in which they are used,
domain names can be hidden within or as part of various types of
references. Email addresses, by contrast, are crucial: use of
names of people or organizations as, or as part of, the email
local part is, for obvious reasons, a well-established tradition
on the network. Preventing people from spelling their names
correctly is, in the long term, inexcusable.  At the same time,
email addresses pose a number of special problems -- they are
more difficult than simple domain names in some respects, but
actually easier in others. This document discusses the issues
with internationalization of email addresses, explains why some
obvious approaches are incompatible with the definitions and use
of Internet mail, and proposes a solution that is likely to
serve users and the network well for the long term.
