Non-MTA machines can have identical configuration. You need a
relayhost:
# [] to disable MX record lookups
relayhost = [smtp.example.com]
And presumably, SASL configuration:
smtp_sasl_password_maps = map with plaintext passwords
smtp_tls_security_level = may
smtp_sasl_auth_enable = yes
smtp_sasl_tls_security_options = noanonymous
And this will almost never need to be updated.
