У меня есть установка postfix 2.11 на Debian jessie с Dovecot SASL, и мне нужен зашифрованный механизм входа в систему для отправки почты через smtp. Для этого в main.cf я smtpd_tls_auth_only = yes набор опций. Я доволен результатами, но хочу разрешить localhost использовать простой текстовый вход без tls-шифрования.
Я не знаю, как установить исключение для localhost. Мне это нужно, потому что когда я отправляю почту с localhost без какого-либо метода авторизации, сообщение доставляется через спам-фильтр spamassassin, который генерирует задержку.
Вот мой main.cf:
smtpd_banner = $myhostname ESMTP
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
