Всем привет!Решил настроить резервный mx сервер, и возникла неожиданная проблема: mail for mail2.kreine.com loops back to myself.
Поясню: mail.kreine.com - основной сервак
mail2.kreine.com - резервный сервак
Вырубаю mail.kreine.com и пытаюсь слать письмо с яндекса на мой домен. Оно возвращается тут же на яндекс с формулировкой mail for mail2.kreine.com loops back to myself.
В логах примерно следующее:
May 2 22:09:46 mail2 postfix/qmgr[8570]: 67141E0E6826: from=<m.kreine@yandex.ru>, size=7007, nrcpt=1 (queue active)

Уже переигрался со столькими вариантами, но.... что-то никак не могу понять, в чём проблема.
Адрес, на который шлю из яндекса, на резервном хосте НЕ создан, только домен в postfixadmin, в настройках которого отмечено, что данный mx является резервным.
Вариант для распечатки
