As Mike alludes to, apart from actually installing postfix ("yum
install postfix"? Not really my distro of choice, CentOS, so I
might've garbled that:-), it should be a matter of running
"system-switch-mail" and choosing PF... really simple, indeed. As
always it is prudent to check that any pathes or default settings
won't trip up the "config move".$$$$$$$
