Hello,
Something like this should work if you use authentication.
accept
authenticated = *
endpass
message = Sending mails from $sender_address_domain is
not permitted
sender_domains = +local_domains
If you are not using authentication, you can simply use:
deny
hosts = +relay_from_hosts
message = Sending mails from $sender_address_domain is
not permitted
sender_domains = ! +local_domains
