Introduction

This guide was first started by Francisco De Zuviría Allende, who was a coworker of mine at Innova|Red  (Argentina's NREN, and also the hosters for this site). When he resigned, I (Guido) got in charge of mail servers, and eventually continued his work on this guide. It was first intended for Debian Lenny, but I thought we could move tu Ubuntu Server Lucid Lynx 10.04 and use newer software. Feel free to use our forums and post any comment!sources

This guide is based  on qmailrocks, but we mixed many sources:

• John Simpson's Site
• Life with Qmail
• The Qsmtp Site & FAQ and It's author's comments
• Qmail Toaster's Site

Goal:

         this guide is oriented to a 500-1500 user, stable mail system with 20 - domains, but can be enhanced to support more. It is both IPv4, IPv6 enabled.

It supports:

• PLAIN (SMTP, POP3 & IMAP)
• CRAM-MD5 (POP3 & IMAP)
• STARTTLS (SMTP)
• SSL (SMTP, POP3 & IMAP)

For better understanding:

• I'm enclosing copy/paste between ===, you should be able to recognize scripts easily that way.
• I'll also be enclosing copy/paste between START PASTE HERE and END PASTE HERE marks
