Постфикс на CentOS - не Может получить электронные письма

Я пытаюсь без успеха установить Постфикс на своем сервере, таким образом, я нуждаюсь в некоторой помощи (новичок здесь).

В основном я не могу получить электронные письма ниоткуда.

Если я посылаю электронное письмо мне или другому адресу в моей сети (например, от john@mydomain.com до jack@mydomain.com) я получаю петлевую ошибку.

Если я посылаю электронное письмо от Google, например, я получаю "Релейный доступ запрещен" ошибка и не могу получить это электронное письмо на моем сервере.

Это (что я думаю, что это), соответствующие файлы конфигурации.

Могли Вы парни смотреть на мою конфигурацию и помогать мне с этим?

Заранее спасибо, Arky
