Topic: Send mail without authentication
How can I modify the config so a user, for example firstname.lastname@example.org could send messages without authentication?
I've tried adding a map "accept_unauth", with the contents:
as the first rule in smtpd_recipient_restrictions, but I only get "Client host rejected: Access denied".
I have also tried with "check_sender_access", same result.
Note: I don't want this to be IP-based.
