Nice, but not as good as a sound argument backed by facts would have
been though.

Should I EXPECT corruption as a day-to-day part of running an exchange
server and allocate extra resources to hunting for it? It sounds like a
lot of EXTRA work, are you a volunteer that doesn't need paying or does
this cost time and money?

I DO HAVE CORRUPT E-MAILS AND DATABASES
I think you read the documentation TOO MUCH. The real world is much
different.
Last Point, my E-mail suggested that people considering using exchange
should get a 120-day eval and try doing backups, restores and repairs
using the microsoft documentation.
If I'm spreading FUD why would I be encouraging users to prove me wrong
and find out that everything I said were lies by doing it themselves?
