postfix / dovecot / mysql не отправляет / не получает электронные письма [дубликат]

Я понимаю, что публиковал это раньше, однако я упустил некоторые очень важные детали, которые, по-видимому, заставили многих людей с меньшей вероятностью ответить, вот более подробная версия.

Моя виртуальная почтовая система postfix / dovecot / mysql не получает почту и не отправляет ее. При отправке он попадает в почтовую очередь. Я в тупике и понятия не имею, что вам предоставить, поэтому, если вы спросите, я поставлю это.

Я использовал это руководство: https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql

My postfix main. cf:

 # See /usr/share/postfix/main.cf.dist for a commented, more complete version

 # line of that file to be used as the name.  The Debian default

А какой файл вам нужен для dovecot?
