Я установил почтовый сервер с Nextcloud, следуя этот учебник. Я создал пользователей и могу читать и отправлять электронные письма из Thunderbird. Я могу читать электронные письма в приложении Nexcloud Mail, но при попытке отправки получаю сообщение об ошибке: Error: Request failed with status code 500.
Я проверил /var/log/mail.log и нашли ошибки связанные со STARTTLS:
mail postfix/submission/smtpd[16292]: connect from localhost[127.0.0.1]
mail postfix/submission/smtpd[16292]: lost connection after STARTTLS from localhost[127.0.0.1]
mail postfix/submission/smtpd[16292]: disconnect from localhost[127.0.0.1] ehlo=1 starttls=1 commands=2
Я так понял конфиг Postfix в /etc/postfix/main.cf должен разрешать соединения с localhost без аутентификации:
smtpd_client_restrictions =
permit_mynetworks
permit_sasl_authenticated
reject_unknown_reverse_client_hostname
smtpd_helo_restrictions =
permit_mynetworks
permit_sasl_authenticated
reject_invalid_helo_hostname
reject_non_fqdn_helo_hostname
reject_unknown_helo_hostname
smtpd_helo_required=yes
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
Почтовые учетные записи в Nextcloud настраиваются с использованием параметров по умолчанию Приложения Auto Mail Accounts:
'auto_mail_accounts' => array (
'imap_host' => 'localhost',
'imap_port' => '143',
'imap_ssl_mode' => 'none',
'smtp_host' => 'localhost',
'smtp_port' => '587',
'smtp_ssl_mode' => 'none',
'email_address_suffix' => ''
),
Поскольку в ошибке упоминается постфикс / отправка, я попытался изменить значения в /etc/postfix/master.cf, например добавление permit_mynetworks или замена permit_sasl_authenticated по permit_mynetworks. Безуспешно.
Вот исходная настройка:
submission inet n - - - - smtpd
-o syslog_name=postfix/submission
-o smtpd_tls_security_level=encrypt
-o smtpd_client_restrictions=permit_sasl_authenticated,reject
-o cleanup_service_name=header_cleanup
изменить: соответствующий журнал из /var/log/nextcloud.log, сообщая мне, что он пытается создать соединение TLS:

edit2: в качестве обходного пути я мог подключиться к серверу smtp, заменив localhost на mail.example.com и используя аутентификацию STARTTLS.
