    Virtual Users And Domains With Postfix, Courier And MySQL (Ubuntu 6.06 LTS) This document describes how to install a mail server based on Postfix that is based on virtual users and domains, i.e. users and domains that are in a MySQL database. I'll also demonstrate the installation and configuration of Courier (Courier-POP3, Courier- IMAP), so that Courier can authenticate against the same MySQL database Postfix uses. The resulting Postfix server is capable of SMTP-AUTH and TLS and quota (quota is not built into Postfix by default, I'll show how to patch your Postfix appropriately). Passwords are stored in encrypted form in the database (most documents I found were dealing with plain text passwords which is a security risk).

    Full Mail Server Solution w/ Virtual Domains & Users (Debian Etch, Postfix, MySQL, DoveCot, DSpam, ClamAV, Postgrey, RBL) This guide describes how to set up a full email solution in Debian Linux (all code is from Debian Etch).  I was asked to design a secure, scalable, portable solution for a small company.  While the guide references many 'servers', the company only had 4 physical machines, Xen was used to virtualize the entire solution.  That particular aspect of the system is not discussed in this guide, although I will try to get it into the next revision.
