I am going to say that machine is overkill. I think 1 CPU (700 MZH+) with
about 512 megs of RAM is more than enough. You have to remember qmail runs
really fast, much faster than sendmail, and does not take much RAM. The only
problem I ever see with qmail, from working with it and reading this list
are IO Bounding problems (The Disks/Controllers can't move fast enought for
qmail).
