I'm not sure if I understood you correctly. Do you want to allow only specific users to send mail, and prevent them from sending mail with arbitrary From addresses? If so: enforce client authentication (e.g. by using submission) and set smtpd_sender_restrictions=reject_authenticated_sender_login_mismatch If that's not what you want: please elaborate some more.
