Yes, but it's considerably more difficult to spoof something than to just
turn it off.
What about these options:
- something in your mail system dies, and the mail can't make it out of
the box
- the alias for root is removed
- a poorly written script trashes all the messages, so nothing is mailed
There's any number of reasons just *not* mailing anything is a bad idea --
it's better to send a note that says, 'Hey, everything checked out okay.'
So long as everything *did* check out okay.
