Собрал стенд (стенд полностью изолирован от внешней среды, все DNS-имена вымышлены и брались от фонаря, также, как и IP-адреса, поэтому на коллизии DNS-имен и IP адресов с настоящими Internet-сервисами прошу не обращать внимания). Итак:
1. Внутри организации: Домен AD: test.local, почтовый домен: test.com.
(Windows Server 2016 + Exchange Mailbox 2016) + (Windows Server 2022 + Exchnge Edge 2019 + DkimSigner 3.4.0).
2. Снаружи, так сказать, в интернете: Почтовый домен: gogo.com, почтовый сервер: MDaemon 23.5.2
3. Все необходимые DNS-записи прописаны, включая PTR. Также присутствуют записи SPF и политики DMARC.
Ну что же... работает DkimSigner. Ниже образцы.

Кто что еще использует в связке с Exchange 2019 для DKIM? |
Вместо (Exchange Edge 2019 + DKIM) можно использовать любой почтовый шлюз, умеющий DKIM. Например Kaspersky Secure Mail Gateway или Proxmox Mail Gateway или еще что-нибудь.
А вообще есть платные DKIM агенты к Exchange. Мне понравился EmailArchitect eaexchdomainkeys. Есть еще DkimX. |
