The Postfix Mail Transfer Agent (MTA) is a high performance open source e-mail server system.

This guide is largely based on Christoph Haas’s great ISP-style Email Server with Debian-Lenny and Postfix 2.5 guide and HowtoForge Groupware Server With Group-Office, Postfix, Dovecot And SpamAssassin On Debian Lenny (5.0), with some packages omitted.

NOTE: Please read all of the information presented in this guide carefully. There are many files and commands that will need to be edited as part of the setup process: please do not simply copy and paste the example blocks.
