Does any other persons use a test on the validity of the MX record of
the sending domain? Not just that there is a MX but also that it is
not a RFC 1918 address or a loopback address?
Yes, we do this with Exim. In fact, what we do is strip invalid
targets from the MX list (i.e. RFC 1918 addresses, loopback nets,
example nets, link-local nets, class D and E ranges). If there's
nothing left, the domain is considered invalid.
