You can probably spend a great deal more, if you shop around. But that is still dirt cheap, for an ISP handling 400,000 messages per day, with the capability to store 8 months of email. Lease on 45K is about $500/mo. Still much, much less than $1 per month. Let say we are going to buy this equipment, and put in the trash after 3 years. Now we in the vicinity of $1600/mo. Still much, much less than $1 per month per user. --Dean
