Why is that a question. You can just do what you said. That said,
you should instead define the internal domains as "relay_domains",
and impement a relay recipient validation table:
main.cf:
indexed = ${default_database_type}:${config_directory}/
parent_domain_matches_subdomains = smtpd_access_maps
relay_domains = example.com
relay_recipient_maps = ${indexed}relay-recipients
relay-recipients:
[email protected] exists
[email protected] exists
...
