Perhaps with a transport table, taking advantage of its
special syntax:
/etc/postfix/main.cf
transport_maps = hash:/etc/postfix/transport
/etc/postfix/transport:
example.org :
* error:we do not deliver this domain

The above will reject SMTP mail, and bounce local submission, for
domains other than example.org.
