             Deployment Issues for Internationalized Email
                      draft-elkchow-iea-deploy-00

Abstract

International Email Addresses (IEA) are far from the global reality. The
current de-facto language of the Internet is English.  Even today, many
of the users of the Internet do not speak English as their primary
language.  The next billion users of the Internet are likely to be even
less familiar with English. IEA is probably the first application needed
in a truly internationalized Internet.   The Email Address
Internationalization (EAI) Working Group defined the RFCs to support
internationalized email.  The time may now finally have come to develop
best practices and to discuss the deployment challenges for IEA.

1  Introduction

   The Email Address Internationalization (EAI) Working Group, which has
   concluded, created a structure and framework for internationalized
   email addresses.  From the charter:

   "The email address has two parts, local part and domain part. Email
   address internationalization must deal with both. This working
   group's previous experimental efforts investigated the use of UTF-8
