You can pretty much fool that. It was suggested before on the list btw.
Make a new MX, pointing to your primary one.

You now have:

10      MX      mx1.domain.net
100     MX      fallback.domain.net

Make that:

10      MX      mx1.domain.net
100     MX      fallback.domain.net
200     MX      alias.for.mx1.domain.net

Bye,
Raymond.
