I see that the sender runs on the same machine as Postfix. Can the
sender be configured to use /bin/mail, mailx, or /usr/sbin/sendmail

Submission through /usr/sbin/sendmail (and therefore /bin/mail and
mailx) can be restricted with authorized_submit_users and spoofing
can be restricted with local_login_sender_maps (Postfix 3.6).
