Я настроил сервер iRedMail с сертификатами SSL на своем компьютере с Ubuntu 18.04, но мне не удается подключить мои устройства (через Outlook или Spark) через протоколы SMTP / IMAP.
Я открыл порты 593, 143, 993, 995 и еще, устройства не могут подключиться к серверу. Ошибка от Spark заключается в следующем: «Не удалось установить стабильное соединение с сервером». Я также пытался руководствоваться руководством , но не повезло.
