Okay I wasn't reading this thread but the last few posts have gone a
little over the edge.

I don't know where this whole "Must have MX record to send email" thing
came from but I would have thought domains that don't want to send email
can easily mark this fact with a simple SPF record:

v=spf1 -all

Trying to overload the MX record is pointless when there is a simple
method that the domain owners, registrars can choose to use or not.
