У меня проблема с настройкой SMTP в NextCloud.
При использовании мастера для настройки файла config.php на порту 25 он работает нормально. Но с SSL / TLS на порту 465 он не работает.
Журнал ошибок в /var/log/exim/main.log:
TLS error on connection from “THE HOSTNAME OF THE SERVER” [MY SERVER IP] (SSL_accept): error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca
Проблема в том, что имя хоста моего сервера не совпадает с именем домена.
Поскольку я не могу изменить имя хоста моего сервера, как заставить Nextcloud использовать mydomain.tld, а не имя хоста? Или может быть проблема в моем конфиге?
Использование Exim4, Dovecot, php7.2, centos7.
Спасибо.
