Be sure that your .procmailrc file does not direct mail back to mbox, or
you'll end up with an infinite loop and diminishing disk space.

The Procmail Companion, a *great* book, shows the use of this command,
and recommends that you rename your mbox file to something else prior to
executing the above command, just in case.
