Welcome to Qmailtoaster's Wiki page.

Background

Introduction

Welcome to the Qmailtoaster wiki. Qmailtoaster is designed to be very stable and easy enough to install that even an inexperienced Linux user can install, operate, and maintain a full blown Qmail MTA.

Everyone is encouraged to find ways to improve Qmailtoaster and to pass their knowledge on to others via the wiki and the email list.

This wiki is maintained by Eric Broch and the rest of the Qmailtoaster community as a means of providing a centralized location for assisting all Qmailtoaster users.

History

QmaitToaster was conceived by Miguel Beccari in June 2002. At the time, Miguel was an IT for Clikka.Com in Udine Italy. Miguel's goals were to provide a very stable rpm based Qmail MTA, and to build a "Qmailtoaster" community of users to support and develop the Qmailtoaster project.
