Отправленные электронные письма проходят SPF и DKIM, но не проходят DMARC при получении в Gmail

Gmail помечает мои сообщения электронной почты как спам. Сообщения проходят SPF и DKIM, но не проходят DMARC. Есть ли какой-нибудь способ заставить мои сообщения проходить DMARC?

Недавно я зарегистрировался на хостинге WordPress в Flywheel, который использует Mandrill для транзакционной электронной почты. На моем сайте есть несколько форм, которые отправляют уведомления по электронной почте при их отправке.

Я прикрепляю исходный источник образца сообщения:
