I'm not a mail administrator, but if the load average is being pushed up this high, I'm wondering whether the problem might be that the load is very bursty, and that the system is intermittently get bogged down. Might it be worth trying to smooth the load somewhat and see if throughput actually goes up? (Like on motorways, where slowing the speed limit from 70mph to 50mph at peak hours results in smoother traffic flow and hence more throughput.) > Pack as much RAM into those puppies as you can afford.

I'd think it's not necessarily "more drive space" but perhaps "faster disks" and "more disks" to keep throughput high and disk contention low.
