Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Squeeze)

Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Debian Squeeze)

This document describes how to install a Postfix mail server 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. Passwords are stored in encrypted form in the database. 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.

WiKID + OpenLDAP + Freeradius Howto

I installed Openldap and freeradius on one (virtual) server and WiKID on another. We believe that this separation of duties is good security policy. In a way it also makes the setup easier because both WiKID and Freeradius listen on port 1812 of the localhost. Both servers are running Centos5.
