Беличья почта сломана

Я новичок в веб-администраторе, и у меня возникла проблема с электронной почтой, которая не могла получать почту, я нашел где-то, что сказал, что переустановка doevcot исправит это, и я так и сделал, и теперь я даже не могу войти в систему для электронной почты.

Я использую Centos 5.6 с Ispconfig 3.

Ниже приводится журнал ошибок:

Я пробовал установить другой почтовый клиент "RoundCube", я удалил и воссоздал для него почтовый домен и почтовые ящики, но все равно ничего. Как будто почтовый клиент (-ы) не может проверить данные пользователя.
