Running a Mail Server Under Linux
by admin | December 11, 2008 | In Linux, Mail server | No Comments
Electronic mail hardly requires an introduction. Communications made
through the original forms of e-mail helped shape the Internet.
Widespread availability of access to e-mail and modern enhancements
such as MIME (Multipurpose Internet Mail Extensions, which allow for
inclusion of attachments and alternate message formats) have helped to
make e-mail the most popular application on the Internet.
With a Linux system and a suitable Internet connection, you can easily set
up your own mail server for personal or business use. This chapter includes
a description of how Internet mail works at the protocol level, and then
guides you through the process of setting up a mail server, complete with
spam and virus filtering. In the final section, you learn how to secure network
communications between clients and your mail server through the use
of SSL/TLS (Secure Sockets Layer and Transport Layer Security) protocols.
The examples in this chapter are based on a Debian GNU/Linux system. (See
Chapter 9 for more information about Debian.) However, much of the
knowledge you gain from setting up a mail server in Debian applies to other
Linux systems as well.
