The general steps to build Postfix from the source files are to
obtain the software bundle, uncompress it, compile it, and install it. The
tools you need are common on nearly all distributions of Unix: gzip, tar,
make, and a C compiler. Postfix
generally expects the GNU
but you can also build it with your platform's native compiler, as long as
it supports ANSI C.
The official Postfix web site (http://www.postfix.org/) has a download link that displays a list of mirrors from which you can get the software. You should select the mirror that is closest to you. Get the package you want by selecting the "Source code" link under either the Official or Experimental release (see Chapter 1). The examples here assume that you have downloaded a file called postfix-2.0.10.tar.gz. If the file you download is different, change the filename accordingly in the commands in the examples.
