So you want to add some loop detection:

    ## deliver seen messages immediately
    :0
    * H ?? ^X-Loop: postmaster
    { SWITCHRC }

    ## find spammy messgages we haven't seen yet
    :0
    *   H ?? ^X-Spam-Flag: YES
    * ! H ?? ^X-Loop: postmaster
    {
      ## ... and tag them
      :0 fw
      | formail -I "X-Loop: postmaster"

      ## now resend the message to postmaster (will get caught in the
      ## recipe above)
      :0
      ! postmaster
    }

I haven't tested this, but it should be pretty close.
