Mail Services (Overview)
Setting up and maintaining an electronic mail service involves complex tasks that are critical
to the daily operation of your network. As a network administrator, you might need
to expand an existing mail service. Alternately, you might need to set up a
mail service on a new network or a subnet. The chapters on mail services
can help you plan and set up a mail service for your network. This
chapter provides links to descriptions of new features in sendmail, as well as a list
of other sources of information. The chapter also provides overviews of the software and
hardware components that are required to establish a mail service.
See Chapter 13, Mail Services (Tasks) for procedural information about how to set up and administer mail services. For
details, refer to Task Map for Mail Services.
See Chapter 14, Mail Services (Reference) for a more detailed description of the components of mail services. This
chapter also describes the mail service programs and files, the mail routing process, the
interactions of sendmail with name services, and the features in version 8.13 of sendmail. See Changes in Version 8.13 of sendmail.
