I say that based on running a small ISP with a few hundred users and see large mail volume. All are business accounts. I'll let others comment on the rest, but I think 500,000 emails per day may be underestimating things. That's only 20 emails per user per day. As to last a few years - who knows. In the past year I've seen such an overall increase in mail volume that now I'm looking to get new servers with more CPU power. It's not disk size that is the problem but the in-coming and out-going traffic that is killing the CPU. Bill -- Bill Vermillion - bv @ wjv . com
