Коллеги, помогите пожалуйста с проблемой.
Есть доменная почта на Яндексе, условно обозначим именем yagroup.ru
С таким же именем group.ru внутренний домен.
Подняли почтовый сервер Debian 11, postfix 3.5.18 на втором уровне домена с именем gkgroup.ru
Ситуация следующая, при отправке на внешнюю почту яндекса, с таким же доменным именем как и внутренний домен (yagroup.ru ) сервер стучится на кд, в итоге получаю Connection refused, status=deferred и висящее в очереди письмо.
Во всех остальных случаях всё прекрасно работает…[spoiler=mail.log]
