Gmail и другие частные серверы помечают законную почту как СПАМ

Конфигурация почтового сервера сводит меня с ума. Письма, отправленные с моего личного сервера, запрещены, опять же Gmail и другими частными серверами.

Я проверил заголовки Gmail и SPF, DKIM и DMARC сдали экзамен. Прикрепленные заголовки заблокированного письма, отправленного и заблокированного почтовым ящиком (отправлено в папку со спамом)
