Agreed. The receiving MTA has to be convinced that the one sending
the stuff is supposed to. What that takes is up to that MTA's admin.

For example, the sender could provide a cerrtificate for the SMTPS
session (I've set up systems like that).

Of course, a random MTA contacting "me" with no MX record is either
misconfigured or (more probably) a low-cost spammer, so I'll tend
to reject that.
