Thank you Viktor.

On the inside mail servers
relay_domains =

On the gateway:
relay_domains = $mydomain

and:
mydomain = example.org

and mx for example.org is at google.

Sending off domain works fine.

Sending to somebody@example.org fails with:
Recipient address rejected: User
unknown in relay recipient table;
