Postfix - невозможно отправить электронное письмо только на сервер Yahoo

Наш сервер не может отправлять электронную почту только на yahoo, dkim, spf работают нормально, также ip очищается из любого черного списка. Еще одна электронная почта Yahoo подойдет лучше всего. Наш сервер может отправлять электронную почту в Gmail, Windows Mail, Яндекс и т. Д.

Очередь почты Postfix:

Я пробовал различные учебники по постфиксам в Google и обращался в службу поддержки Yahoo. Здесь я вижу проблемы, но безрезультатно.
