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

163 regenerates all the other makefiles in the build tree. If you wish to
164 use additional software such as a database back-end for virtual users,
165 or TLS/SSL authentication, you will need to regenerate the makefiles
166 using one or more of the appropriate <envar>CCARGS</envar> and
