Even when the hardware is enough, I enjoy a new machine when it comes to build a mail server: it is such a critical machine (users will not understand that their mailbox could be out of reach for 5 minutes) with enough different components, each having specificities on the config (not the sort you power one and you are done) I don't feel at ease doing too much modif on a production email server. Now at 10K$ you have plenty of money, I believe you could afford 2 machines for hi availability. Olivier
