35 The <application>Postfix</application> package contains a Mail Transport
36 Agent (MTA). This is useful for sending email to other users of your host
37 machine. It can also be configured to be a central mail server for your
38 domain, a mail relay agent or simply a mail delivery agent to your local
39 Internet Service Provider.

117 will be expected to be in place during the installation. Add the users
118 and groups with the following commands issued by the

144 regenerates all the other makefiles in the build tree. If you wish to
145 use additional software such as a database back-end for virtual users,
146 or TLS/SSL authentication, you will need to regenerate the makefiles
147 using one or more of the appropriate <envar>CCARGS</envar> and
148 <envar>AUXLIBS</envar> settings listed below.
