Generally you will do better here by consulting the documentation
first, asking specific questions about what you did not understand.
DEBUG_README.html has a section with advice about posting here.

A check_sender_access lookup, and possibly also see the
RESTRICTION_CLASS_README.html document. Note the futility of sender
address based controls, because of forgery. Perhaps you need SASL AUTH
and smtpd_sender_login_maps and reject_*sender_login_mismatch
restrictions? With an incomplete problem description, we can only
guess.

A check_recipient_access lookup, and possibly also see the
RESTRICTION_CLASS_README.html document. There could be other
possibilities depending on address class of the "Local Domain". See
ADDRESS_CLASS_README.html.
