    No, reject_unlisted_recipient has nothing to do with the MAIL FROM; it is
    used to "reject the request when the RCPT TO address is not listed in the list
    of valid recipients for its domain class".

    You are (again) confusing two different parameters; one pertains to SENDER
    and the other to RECIPIENT.

    No. Carefully re-read the relevant sections of postconf(5):
    http://www.postfix.org/postconf.5.html#reject_unlisted_recipient
    http://www.postfix.org/postconf.5.html#reject_unlisted_sender
    http://www.postfix.org/postconf.5.html#smtpd_reject_unlisted_recipient
    http://www.postfix.org/postconf.5.html#smtpd_reject_unlisted_sender
