Abstract

There are many howtos in the Internet about setting up mail servers and various people has various choice of MTAs. Some like, Qmail, while some like Postfix or Exim. I have been using Qmail for long time and it is an excellent MTA. The way the Qmail is licensed and distributed that there are no binary packages so that users can easily setup with their favorite distribution, and installing basic Qmail setup even is very difficult since users need applied various patches and tweaks etc. With all these hassles Qmail is the preferred choice of many geeks. The decision behind this guide is to use Postfix,an equally secure and fast MTA like Qmail, it is easy to configure and setup a basic system in any Linux distribution. Postfix has many add-ons and support Maildir format, PostgreSQL and MySQL backend for storing and managing virtual domains very easily. This setup will be a complete virtual mail domain systems , with anti-virus and spam filtering for ISPs , hosting companies, and individual corporations who wish to use Ubuntu Linux as there preferred server platform.

Also many ideas of this howto was stolen from Gentoo Wiki's A Complete Virtual System, an excellent howto once again from Gentoo Linux community, and without them I wouldn't have been able to extend this howto for Ubuntu community.
