Nowhere, you create one yourself.  Very very carefully, because these
rules will be applied to *all* incoming local email.

The manpage of procmail(1) explains where Procmail will look for
filtering rules:

    If  no rcfiles and no -p have been specified on the command line,
    procmail will, prior to reading $HOME/.procmailrc, interpret
    commands from /usr/local/etc/procmailrc (if present).  Care must be
    taken when creating /usr/local/etc/procmailrc, because,  if
    circumstances permit,  it will  be  executed  with  root privileges
    (contrary to the $HOME/.procmailrc file of course).

For example, in your system-wide `procmailrc' file you can use rules
like the following:


    :0 H
    * ^X-Spam-Flag: YES

    :0 H
    * ^Subject: {Spam not delivered}

    :0 H
    * ^Subject: {Possible Spam}

The "/." suffix of the folder names means they are MH-style mail
folders.  You can also use a plain "/" suffix for Maildir folders,
or no suffix at all for plain Unix mbox-style files.
