Welcome to Postfix. What we're going to attempt to do is to pass on what information is available right now on installing and configuring the Postfix MTA on Red Hat Linux. We will be exploring best practice and usage conventions for three primary environments. The home user, the office, and the ISP. All assumptions are based upon the usage of Red Hat Linux 6.1 (Cartman) but should be applicable to Red Hat Linux 6.2 (Zoot), as well.
