Hello! A quick question (I think).
According to the Postfix Manual, "reject_unlisted_recipient": > "Reject the request when the MAIL FROM address is not listed in the list of > valid recipients for its domain class." > and "smtpd_reject_unlisted_sender": > "Request that the Postfix SMTP server rejects mail from unknown sender > addresses, even when no explicit reject_unlisted_sender access restriction > is specified." > So, If I have in my main.cf: smtpd_reject_unlisted_sender = yes, then, I don't need to include the reject_unlisted_recipient rule at the smtpd_recipient_restrictions, right? If I use that rule (either one), and someone is trying to send a mail to a local account from for example hotmail, gmail, or any other external server, means that it will be rejected??? because the FROM address is not listed in the local recipients. Is that true? Thank you!
