Abstract

This paper presents a classification for e-mail routing issues. It

clearly defines commonly used terminology such as static routing,

store-and-forward routing, source routing and others. Real life

examples show which routing options are used in existing projects.

The goal is to define all terminology in one reference paper. This

will also help relatively new mail system managers to understand the

issues and make the right choices. The reader is expected to already

have a solid understanding of general networking terminology.

In this paper, the word Message Transfer Agent (MTA) is used to

describe a routing entity, which can be an X.400 MTA, a UNIX mailer,

or any other piece of software performing mail routing functions. An

MTA processes the so called envelope information of a message. The

term User Agent (UA) is used to describe a piece of software

performing user related mail functions. It processes the contents of

a message's envelope, i.e., the header fields and body parts.
