Abstract

The discussion of a transition from the current ARPANET sndmsg environment and mechanisms to a more general internet environment and richer mechanisms must consider techniques for continued activity during the transition. In addition, there is a current need for a mechanism to support the interaction of the several already existing NSW-like message environments with the ARPANET message environment.

Out-of-Net Host Addresses for Mail

There is now interest in sustantially extending the scope of the

computer mail system used in the ARPANET to allow communication of

voice, fax, graphics, as well as text information between users in

different networks as wells as within the ARPANET.

The discussion of a transition from the current ARPANET sndmsg

environment and mechanisms to a more general internet environment and

richer mechanisms must consider techniques for continued activity during

the transition. In addition, there is a current need for a mechanism to

support the interaction of the several already existing NSW-like message

environments with the ARPANET message environment.

This memo discusses some possible alternatives for computer mail

addressing for hosts outside the ARPANET in the short term. This memo

is hopelessly Tenex oriented in its descriptions and examples.

It helps to keep a few goals in mind while considering the alternative

solutions:

Goals:

1) Minimum Change to Existing Software.

2) Maximum User Acceptance.

3) Maximum Compatibility with the future Internet Message

Environment.

4) Minimum Special Transition Software.

These goals are to some degree incompatible, so the evaluation should be

expected to involve a trade off.

At this point, it would be good to have a model of the current situation

and mechanisms of the ARPANET message environment. It is assumed the

reader understands it well enough to dispense with a long description of

how a message gets from A to B. The important thing is to note the

types of players in the picture. There are:

message composition (or sending) programs (e.g., Hermes, SNDMSG), in

general there are several message composition programs for each type

of operating system or host in the network,

mailers,

mail servers (i.e., FTP servers) that receive the mail coming into at

host and deposit it in mailboxes,

message processing (or reading) programs (e.g., Hermes, MSG, RD), in

general there are several message processing programs for each type

of operating system or host in the network, and note that the more

developed mail are both reading and sending programs.

Messages are transmitted as a character string to an address which is

specified "outside" the message. The destination host ("YYY") is

specified to ...
