so, let me get this straight. you think that this set of information
is _convincing_? the fact that microsoft's own mail servers average
25 days between reboots/crashes/cycles/whatever is convincing enough
for me, as a corporate customer, _not_ to chose NT.

i told mary about NT being tested for us in a nuclear control facility
and she said "god save us all!".

note that i've cc'ed mary on this message - she'll probably receive
it sometime _tomorrow_. guess what mail service they are running...

ps. why the hell does microsoft need > 30 mail servers? for the same
reason that kaiser needs one fragile nt server per a couple hundred
users, i'd expect. so... m$'s 20,000 employees / 500 (generous)
accounts / server ~= 40 or 50 systems just for mail servers? <sigh>
