Ошибка при отправке электронной почты (с contact@example.com на contact@example.com с ответом на (ответ на заголовок) на undefined)

У меня есть сайт Drupal 8, установленный на сервере Ubuntu 18.04 с PostFix.

Я могу отправлять и получать электронные письма, но сервер не может отправлять уведомления самому себе.

Адрес почтового сервера: contact@example.com.

Если пользователь использует контактную форму на моем сайте, я получаю такую ​​ошибку:

Ошибка при отправке электронной почты (с contact@example.com на contact@example.com с ответом на (ответ на заголовок) на undefined)

Как я могу это исправить ?

Вот исходный код электронного письма, отправленного с contact@benefitime.com на contact@s1biose.com

Он работает.

Но когда drupal уведомляет или пользователь использует контактную форму, сайт отправляет с contact@benefitime.com на contact@benefitime.com, это не работает.
