  If an MTA is shared, the reputation would seem to be shared, too.
That's life.

  We could require that abuse of a shared MTA by one domain not affect
the reputation of another domain also at that MTA.  But we can't use
the HELO field as part of a solution to meet that requirement, as the
only information it presents is the name of the shared MTA.

  If the *message* is authenticated, and not the *transport* layer,
then it doesn't matter how the message is transported.  But that's
another issue...
