Purpose of this document

|
|
========================
|
||
|
|
|
||
|
|
This document provides a road map of the Postfix mail system source
|
||
|
|
code distribution. I suggest that you take a few minutes to read
|
||
|
|
it, and then proceed with the installation instructions.

Introduction
|
||
|
|
============
|
||
|
|
|
||
|
|
This is the first public release of the Postfix mail system. Thank
|
||
|
|
you for your interest in this project. Send me a postcard if you
|
||
|
|
like it. My postal address is below.
|
||
|
|
|
||
|
|
You must read the LICENSE file, if you didn't do so already. A copy
|
||
|
|
of the LICENSE must be distributed with every original, modified,
|
||
|
|
complete, source, or binary copy of this software or parts thereof.
|
||
|
|
I suggest that you keep a copy of the file in /etc/postfix/LICENSE.

Purpose of the Postfix mail system
|
||
|
|
==================================
|
||
|
|
|
||
|
|
Postfix aims to be an alternative to the widely-used sendmail
|
||
|
|
program. Sendmail is responsible for 70% of all e-mail delivered
|
||
|
|
on the Internet. With an estimated 100 million users, that's an
|
||
|
|
estimated 10 billion (10^10) messages daily. A stunning number.
|
||
|
|
|
||
|
|
Although IBM supported the Postfix development, it abstains from
|
||
|
|
control over its evolution. The goal is to have Postfix installed
|
||
|
|
on as many systems as possible. To this end, the software is given
|
||
|
|
away with no strings attached to it, so that it can evolve with
|
||
|
|
input from and under control by its users.
|
||
|
|
|
||
|
|
In other words, IBM releases Postfix only once. I will be around
|
||
|
|
to guide its development for a limited time.
|
||
|
|
|
||

|
This release could not have happened without the input from a team
|
||
|
|
of competent alpha testers. Their names appear in numerous places
|
||
|
|
in the HISTORY file. I appreciate the input from my colleagues at
|
||
|
|
the IBM Global Security Analysis Laboratory: Paul Karger, Dave
|
||
|
|
Safford, Douglas Schales, and Leendert van Doorn. I also appreciate
|
||
|
|
the support by Charles Palmer under whose leadership I began this
|
||
|
|
project, and who had the privilege to name the software, twice.

Roadmap of the Postfix source distribution
|
||
|
|
==========================================
|
||
|
|
|
||
|
|
Point your browser at html/index.html for Postfix documentation,
|
||
|
|
for manual pages, and for the unavoidable Postfix FAQ. Expect to
|
||
|
|
see updated versions on-line at http://www.postfix.org/
|
||
|
|
|
||
|
|
Point your MANPATH environment variable at the `man' directory (use
|
||
|
|
an absolute path) for UNIX-style on-line manual pages. These pages
|
||
|
|
are also available through the HTML interface, which allows you to
|
||
|
|
navigate faster.
|
||
|
|
|
||
|
|
The RELEASE_NOTES file describes new features, and lists incompatible
|
||
|
|
changes with respect to previous Postfix versions.
|
||
|
|
|
||
|
|
The INSTALL file provides a step-by-step guide for building and
|
||
|
|
installing Postfix on many popular UNIX platforms.
|
||
|
|
|
||
|
|
The COMPATIBILITY file lists features that Postfix does or does
|
||
|
|
not yet implement, and how well it works with other software.
|
||
|
|
|
||
|
|
The HISTORY file gives a detailed log of changes to the software.
|
||
|
|
|
||
|
|
The PORTING file discusses how to go about porting Postfix to other
|
||
|
|
UNIX platforms. Some people are looking into a port to Windows NT.
|
||
|
|
We'll see. This software uses every trick in the book that I learned
|
||
|
|
about UNIX.
|
||
|
|
|
||
|
|
The TODO file lists things that still need to be done. If you want
|
||
|
|
to set your teeth into one of those problems, drop me a note at
|
||
|
|
wietse@porcupine.org to avoid duplication of effort.
