Sorry, I should have added what we are looking at as far as load and
userbase. We have about 3000 mail accounts on the server, and would like
to think in terms of building for a larger base of about 6000 or so. We
have the equipment all housed at a colo facility. The hardware is so-so.
Dual PIII's with Asus VP6 motherboards and a gig of ram if any of that
info is userful.
