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.
