Correct, provided that you are set up to route to such domains. There
are some ISPs that want that facility. It is not the default!

Er, sender_host_accept_relay for controlling hosts. But that is for
controlling *outgoing* (to anybody from specific hosts) relaying,
whereas relay_domains and relay_domains_include_local_mx is for
controlling *incoming* relaying (from anybody to specific domains).
