This document describes how to set up the Zimbra Collaboration Suite (ZCS) Open Source Edition v5.0 on Debian Etch. The resulting system provides a full featured collaboration-suite with many features that I cannot list all here - please have a look at the feature list. It also comes with a nice (themeable) AJAX web interface for administration and user access.

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 will 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 will 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.

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.

This tutorial shows how to set up a Gentoo 2007.0 based server that offers all services needed by ISPs and hosters: Apache web server (SSL-capable), Postfix mail server with SMTP-AUTH and TLS, BIND DNS server, Proftpd FTP server, MySQL server, Courier POP3/IMAP, Quota, Firewall, etc. This tutorial is written for the x86 version of Gentoo 2007.0, but should apply to other architectures with very little modification.

This document describes how to install the Dovecot mail server from source as an imap / pop3 mail server for your domain and how to set up the sieve plugin so your clients can use the sieve mail filtering language for their mail accounts.

In this tutorial I will show how you can set up a Postfix mailserver as a backup mail exchanger for a domain so that it accepts mails for this domain in case the primary mail exchanger is down or unreachable, and passes the mails on to the primary MX once that one is up again.

This tutorial shows how you can import Outlook Express emails, contacts, and account settings into Mozilla Thunderbird and Evolution. This is quite useful if you want to switch from Windows to Linux but don't want to lose your mails and address book. The procedure should be similar if you use Outlook instead of Outlook Express.
