This page will show you how to setup a mail server with antispam and antivirus capabilities and can be integrated into Active Directory.

How to install Linux

You can use either Red Hat Enterprise Linux 4 or CentOS 4. This guide will also work with CentOS 4.1, 4.2, 4.3, 4.4 and 4.5. RHEL 4 can be purchased from Red Hat and comes with support. CentOS 4 on the other hand can be downloaded here.

NoteTo simplify our administration tasks, log in as the user root and specify your root password. This is not the recommended way of administering a Linux box, but for the tasks at hand it is the most efficient way.

How to install SMTP, POP3, IMAP and WebMail service

These are the standard mail services and the guides below will show you how to install them.

How to create mailboxes, aliases and distribution groups

WebminInstall Webmin if you want a web-based interface to manage your mail accounts.

How to add antivirus and antispam filtering

These are great add-ons that will benefit your mail users.

NoteYou can greatly reduce the volume of spam and viruses reaching your mail server if you are willing to give up something. If you are willing to have your mail delayed (time), install Postgrey. If you are willing to spend (money), get the Barracuda Spam Firewall.

ImportantBefore deploying your new mail server, see Mail Server Checklist to ensure your new mail server will have a good sending reputation and can be trusted.

How to integrate Active Directory

Integrating Active Directory into your mail server will turn your Linux email server into a lean and mean Exchange like server.
