New version. Mostly cleanup. Adopted ADministrative Management Domain (ADMD)
as the latest term for what a Boundary MTA sits at the edge of.
Comments eagerly solicited.

Title : Internet Mail Architecture

Over its thirty-five year history Internet Mail has undergone
significant changes in scale and complexity, as it has become a
global infrastructure service. The first standardized architecture
for networked email specified a simple split between the user world,
in the form of Mail User Agents (MUA), and the transmission world, in
the form of the Mail Handling Service (MHS) composed of Mail Transfer
Agents (MTA). Core aspects of the service, such as mailbox address
and basic message format style, have remained remarkably constant.
However today Internet Mail is marked by many independent operators,
many different components for providing users service and many others
for performing message transfer. Public discussion of the
architecture has not kept pace with the real-world technical and
operational refinements. This document offers an enhanced Internet
Mail architecture to reflect the current service.
