Use the "var ??" syntax:

        :0
        * ^Header:[     ]*\/[^  ].*
        * MATCH ?? something
        ...

That probably doesn't do what you think it does.  If you want to
throw out a message, just deliver it to /dev/null:

        :0
        * conditions
        /dev/null

OR, set the HOST variable to anything but your machine's hostname, or
unset it:

        :0
        * conditions
        { HOST }

To search for 5 or more instances of something in a procmail regexp,
just put five copies in a row.  (If there are more than five present,
then a match on five of them will obviously succeed.)
