Mail Server. The course provides:labs that can be performed on a practice
server, flash movies that demonstrate configuration of Postfix, live virtual
classroom sessions with an instructor and each student is provided a practice
server. The Postfix Mail Server course for $595.00 is 5 weeks long(wo hours each week), performed one-on-one

Postfix Mail Server: Course Design
Information - 400 pages of training
The manual is a 400 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 a CD which will allow them 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 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. Each student will be provided a practice server for 5 weeks.
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.
Cyrus-Imap -
Cyrus-Imap is a secure but difficult Mail Delivery Agent (MDA) that is
discussed in detail. This section covers basic installation, the admin
user, creating users, administering users, access control lists, logins,
realms, mailbox quotas, sasld authentication, troubleshooting, authentication
failure, tcp_wrappers and SELinux.
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.
