The front-end MTA (mta-rx) should be the one checking for validity
of sender and recipient addresses. Once the message is accepted,
there is no point in bouncing it by a back-end MTA (mta-tx).

The mta-tx should not be more restrictive in its decisions to accept mail
that the front-end MTA. Actually most of the checks are not needed
nor desired at mta-tx.

No, fix the core problem.

I sincerely hope there is. See README_FILES/README.sendmail-dual
(in the amavisd-new documentation) for some hints.
