Postfix Mail Server: Course Design
Information - 500 pages of training
The manual is a 500 page 11x8.5" lay flat manual for Postifx with step by step configuration.
Labs - The labs are provided to give you step-by-step references on how to configure a server and how to set up Postfix.
Flash Movies with Voice - Each student is provided access to watch Flash Movies with voice to demonstrate how to set up and maintain a Postfix server.
Live Virtual Classroom - Students will have one-on-one sessions with an instructor to demonstrate Postfix configuration and so that students can ask questions. These virtual classrooms allow students to talk to the instructor using our voice server and allow them to watch live demonstrations on a live server.
Live Practice Server - Students are each provided a server(VMWare image) to work on during the class. They will have root access so that they can build a Postfix Mail Server. The instructor can then login and evaluate the server and verify the student's settings.
Postfix Portal - The Postfix Portal provides updates to the training material and access to new movies which are created so the student can not only get trained on how to install and manage a Postfix Mail Server but also have access to new technologies and ideas as they are developed. This is an important way of continually battling new SPAM techniques and Malware attacks.
Postfix Mail Server Course Outline
Introduction to Mail Servers - The Introduction describes the theory and structure of how mail is transferred on the Internet.
Postfix Design - The modular design is described with a focus on how mail is transported within Postfix in order to understand the process and path of mail within Postfix.
Basic Configuration - There are several key features that must be set correctly for Postfix to run, including making Postfix the default server, setting the identity of the server, configuring network settings and aliases needed for Postfix. Once that is complete the course demonstrates ways to check the configuration. This section concludes with methods for evaluating logs, mail limits, queue management and a list of Postfix commands. Special attention is given to the description of Lookup Tables and Maps which Postfix uses to read information and settings.
SMTP Restrictions - Simple Mail Transport Protocol (SMTP) defines the way may is transferred between mail servers. Requiring mail servers to follow standards that are set reduces SPAM on the Postfix server. These restrictions which when they are instituted will dramatically reduce the amount of SPAM on your mail server. These restrictions include, communication in the envelope, restrictions on hostname, recipient restrictions, restrictions on the envelope sender,requisition of an existing domain, restrictions on the envelope recipient, and recipient names. Managing these restrictions correctly will save resources, thus money, when employing a Postfix Mail Server.
Control Relays - Relay control is a way to restrict who can send mail through your mail server and is an important step in protecting Postfix from sending SPAM.
Controlling SPAM - Specific methods of controlling SPAM are discussed in tis section. SPAM control methods include; client detection rules, forged addresses, non-routable networks, blackholes, and address sender verification.
Dovecot - Dovecot is the secure alternative to Cyrus-IMAP and this section will demonstrate how to configure and employ Dovecot in various situations.
IMAP and SquirrelMail Install
Web based mail is a popular choice and SqurrelMail is one of the easiest alternatives to configure for web based email. This section will discuss the requirements, configuration and settings for SquirrelMail.
Hosting Multiple Domains - This section will describe the steps to separate domains with virtual accounts, create virtual ownership, using virtual domain aliases, creating users, setting IP configurations and providing the configuration required for Cyrus-IMAP or Dovecot to host multiple domains. Examples for configuring MySQL to be used with virtual domains is provided.
Mobile Users and SMTP Authentication - This section describes how to configure that option so that qualified users may authenticate and receive mail from anywhere. This section includes SASL authentication, server-side authentication, and relay permissions.
SMTP AUTH and Microsoft Outlook Express - The popular use of Microsoft Outlook and Outlook Express may require you to configure your Postfix Mail Server to be able to service these clients. This section show you how to set that up.
Intro to TLS and SSL - Transport Layer Security (TLS) and SSL are options to provide encrypted email and logins. This section will show you the differences and demonstrate how to configure TLS the more secure option. This will include configuring Dovecot, SquirrelMail, Zimbra Desktop and other client options.
Provide SPAM and Virus Control - Amavisd is configured to provide an option to scan for SPAM and virus activity when mail arrives on the Postfix server. This section will describe the installation of SpamAssassin, ClamAV, the configuration of Perl modules needed for Amavisd, SpamAssassin rules, how to modify SPAM rules, discard SPAM, tests, and virus signature updates as well as whitelists and blacklists for SPAM.
Postfix Mail Gateway - Postfix is commonly used to create a secure Gateway for Microsoft Exchange servers. This section will show you how to set that up and to secure it for safety. It will also include how to set up a Virtualized Mail Gateway.
Postfix Statistics - This section will demonstrate scripts that can be run to gather statistics for the mail server. This will provide you with detailed information about specific users and how they are using their mail.
Postfix Security - The mail server is in a very hostile environment. This section will show you how protect your mail server for various kinds of attack. It will also discuss how to limit attacks by limiting country subnets.
Troubleshooting - Specific and common problems are discussed in this troubleshooting section. Examples: Problem: virtual_alias.db Does Not Exist Problem: Wrong Transport Problem: No Local Recipient Maps for Virtual Domains
Mail Clients - Various mail clients and their advantages are discussed in order to provide options.
Practical Examples - This section lists a number of specific configurations that you can use for specifc Linux distributions. This will enable you to quickly configure and running a mail server for your specific needs quickly.
