Is this machine receiving inbound mail from the Internet, or sending
outbound mail from internal users? Or both?

Why do you want to accept mail from invalid domain-less envelope
senders? A reasonable minimal configuration is:
smtpd_recipient_restrictions =
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
reject_non_fqdn_sender,
reject_unknown_sender_domain
Allows non-fqdn addresses from trusted clients and authenticated
users, but not from outside. You'd generally add more to that,
and be mindful of "smtpd_relay_restrictions" introduced with 2.10
or so.
