Не сохраняются письма Dovecot IMAP?

Всем Привет!

Имеется система Ubuntu Server 16.04 c почтовым сервером (Postfix+Dovecot+MySQL)

Проблема в том, что на клиентах (ThunderBird) периодически не хочет сохранять отправленные письма.

'imaps' protocol is no longer necessary

Прочитайте документацию именно по вашей версии dovecot. Не стоит тупо копипастить, или обновляться без чтения ReleaseNotes. В первом случае используете устаревший плагин, который не создает вам необходимые папки для Thunderbird папки, во втором не указали сертификат центра сертификации, в третьем поменялся формат файла конфигурации, и шифрование теперь указывается другим способом.

И научитесь пользоваться гуглом.

Как минимум, у вас старая версия конфига, о чём dovecot вам и сообщает. Сконвертируйте конфиг в новый формат, уйдёт куча предупреждений из логов, и будет проще понять, в чём проблема.

Из процитированных вами логов никаких таких проблем, связанных с СОХРАНЕНИЕМ писем в ящик, не следует.
