This is the relevant portion of main.cf from a system I use that only accepts local mail and relays all of it. I'm using transport maps for the relay bit, but relay host should work the same way -- both are applied after mail is accepted.

mydomain_fallback = localhost
mynetworks = 127.0.0.0/8, [::1]/128
smtpd_client_restrictions = permit_mynetworks permit_sasl_authenticated permit
inet_protocols = all
inet_interfaces = loopback-only
transport_maps = hash:/etc/postfix/transport
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_tls_security_level = encrypt
smtp_sasl_mechanism_filter = !gssapi, plain, login
smtp_sasl_security_options = no anonymous
