How to: install postfix on slackware

Please do not use these instructions on a production environment, without testing them before. These instructions does not include configuration steps, but I’ll post them  later. All you need for this setup is a “full” installation of a slackware linux 12 (other versions should do as well) with internet connection.

This page is a slightly updated and slackware specific version of the following page: http://www.postfixvirtual.net/postfixvirtual.html#introduction
