It's a gut feeling based on systems I've worked on and talking
to other people about thier machines. Another number to throw
into the mix ;] on most free email sites, only 10% to 20% of
the accounts are active. (based on that - i'm probably
overstating the amount of 20K)
We did some measurements with a similar machine as above. About
the same hardware except it had 128Mram. Only doing outgoing
email, for newsletter type mail. It was able to sustain about
750,000 emails per day. It ranged from 500K to 1.1M.
