Почта доставляется, но не отображается на клиенте

У меня следующая настройка почтового сервера (dovecot --version = 2.2.13, postfix version = 2.11.3-1), псевдонимы пользователей хранятся в mariadb, а проверка подлинности выполняется против активного сервера каталогов. Кажется, все в порядке (поиск псевдонимов, NTLM-аутентификация и т. Д.), Но не доставка. Кажется, что почта доставляется в почтовый ящик правильно, но не доходит до клиентов.
