The problem IS NOT with defining the "login_maps" table, rather it is
with attempting to use the associated restriction!

    reject_sender_login_mismatch

and related restrictions.  This restriction should only be used on the
submission ports, while on port 25, where SASL should be disabled, there
is never a SASL username, so a "match" is never possible.

If you want to disallow some sender addresses, use "check_sender_access".
