Ostatnio robiłem aktualizację jednego z serwerków z lenny->squeeze->wheezy
dziś zauważyłem, że postfix kompletnie olewa smtpd_sender_restrictions
Konfiguracja: postfix, normalni użytkownicy, courier, amavis, sasl. itp.
W linijce smtpd_sender_restrictions mam: reject_unknown_sender_domain, reject_sender_login_mismatch, permit_mynetworks, permit_sasl_authenticated
Mogę sobie dla użytkownika sprawdzonego przez sasl zmienic nazwe jego domeny na nie instniejącą i wiadomość wychodzi, zmienić na innego usera (reject_sender_login_mismatch) i wiadomość wychodzi. O co może chodzić?
Próbowałem komentować permit_my_networks, permit_sasl_authenticated ale nic to nie daje, ogólnie najbardziej mi zależy na tym, żeby userzy authenticated nie mogli zmieniać pola From:
