About Sendmail
Sendmail is a mail transfer agent (MTA) used for delivering mail across networks.
It is a well known project of the open source, free software and UNIX
communities. Sendmail is distributed both as free software and proprietary
software, and is a standard MTA under many variants of the UNIX operating
system.
These instructions were written for version 8.13 of Sendmail. Other versions may
have different settings. This chapter includes steps to route mail to Outbound
Services and is designed to work with most major Sendmail deployments.
You can also set up Private Outbound DNS to route mail to Outbound Services.
Private Outbound DNS is often simpler and more reliable than a smarthost
installation. Private Outbound DNS is described in “Option 1: Set Up Private
Outbound DNS” on page 16. For more information, see your mail server product
documentation for information on changing your DNS settings.
