  A: don't run SMTP.

    Which is a temporary error to SMTP.

      yup.  so what?
      you want the DNS to act as a trusted third party?
      sounds like an attack vector to me.

        So does turning off the smtp service and sending lots of
        email to that email domain.  Look at what happens when
        google, hotmail etc. temp fail all email to them because
        of some spam that came from a host without actively attempting
        to fill up the mail spools.
