Minimum OS Requirement to run Qmail

[Andrew Buenaventura]

I am going to setup a dedicated linux box that will run qmail only.  What is
the most minimum package that I need to install from Red Hat 7.0 to be able
to run Qmail? I do not want unnecessary services/daemons running on that
box.  I will also be installing the web based email package that runs on
qmail.
