1) To avoid "relay access denied" errors, decide if the domain is
in the local class (mydestination) or in some other address class
as defined in ADDRESS_CLASS_README.
2) To avoid "user unknown" errors, provide the recipient address
validation as required by ADDRESS_CLASS_README.
3) Optionally, use transport_maps to redirect some recipients as
in your example.
