not what you want but perhaps workaround
do sender verify via tls ( untested total )
smtpd_sender_restrictions = hash:/etc/postfix/sender_access
/etc/postfix/sender_access:
exmaple.com reject_unverified_sender
address_verify_default_transport = verify_tls
verify_tls unix - - n - - smtp
-o smtp_tls_security_level=encrypt ( or what you like )
no idea if this will work, for more advanced answers wait gurus response
Best Regards
