Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 8.04 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). In addition to that, this tutorial covers the installation of Amavisd, SpamAssassin and ClamAV so that emails will be scanned for spam and viruses. I will also show how to install SquirrelMail as a webmail interface so that users can read and send emails and change their passwords.

How to add two-factor authentication to Google Apps for your Domain using open source software
Everybody loves GMail. With Google Apps for you Domain, you can use GMail with your own domain, allowing organizations to outsource their email - and the requisite anti-spam filtering to Google. Webmail is very convenient, but for frequent travellers and those who use public wifi, it can be quite dangerous. Logging in from a kiosk or shared computer is a sure way to get your username and password stolen by a keystroke logger. Using a public WiFi system can lead to a man-in-the-middle attack. In this document we will take advantage of two open source projects to add two-factor authentication to Google Apps. The first is Gheimdall, a a TurboGears project for Google Apps SSO service. Gheimdall supports PAM and LDAP authentication natively. It also includes sample code to add new authentication methods, which made it very easy to add two-factor authentication from WiKID. WiKID is a dual-source two-factor authentication solution that uses public key cryptography to strongly authenticate users.
