Я использую Ubuntu 12.04 на Линоде с Postfix и opendkim.
Моя подпись DKIM проверяется / проходит, когда я тестирую по адресу http://www.brandonchecketts.com/emailtest.php, но не получается, когда я тестирую с autorespond+dkim@dk.elandsys.com.
Проблема связана с правильным поиском записи DNS. Elandsys тест смотрит запись DNS неправильно . Я предполагаю, что это проблема с моей конфигурацией, и я хотел бы знать, как ее исправить.
Тест на brandonchecketts.com ищет запись DNS правильно, используя:
Построение DNS-запроса для list._domainkey.my_example.common
Тест на elandsys ищет запись неправильно, используя:
нет записи DNS для _domainkey.list.my_example.com
Моя таблица подписи opendkim включает эту запись:
*@list.my_example.com list._domainkey.my_example.common
Моя таблица ключей opendkim содержит следующую запись:
list._domainkey.my_example.com list.my_example.com:list:/etc/opendkim/list.private
Я опубликую два теста подробно ниже. Первый показывает правильность проверки DKIM. Второй показывает проблему, о которой сообщает elandsys.

Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different. I believe autorespond+dkim@dk.elandsys.com is broken. That appears to be the problem. Unless it gets fixed, just don't use it. Use the others.
Our DKIM is passing:
The only test it is failing is:
