Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 12.04 LTS)

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, 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. I will also show how to install SquirrelMail as a webmail interface.

Securing Your ISPConfig 3 Installation With A Free Class1 SSL Certificate From StartSSL

Tue, 17 Jan 2012 17:50:17 +0100

Securing Your ISPConfig 3 Installation With A Free Class1 SSL Certificate From StartSSL

This tutorial shows how you can use a free Class1 SSL Certificate from StartSSL to secure your ISPConfig 3 installation and get rid of self-signed certificate warnings. The guide covers using the SSL certificate for the ISPConfig web interface (both Apache2 and nginx), Postfix (for TLS connections), Courier and Dovecot (for POP3s and IMAPs), and PureFTPd (for TLS/FTPES connections). If you've installed monit and use HTTPS for its web interface, I will show you how to use the StartSSL certificate for it as well. This guide assumes you use Debian or Ubuntu; the principle is the same for other distributions supported by ISPConfig 3, but paths might differ.
