Вторичный DNS устарел

У меня есть первичный DNS-сервер на моем сервере FreeBSD ns0.dddddd.eu и вторичный DNS-сервер на Xname.org.

Но вторичные DNS на Xname.org устарели! Команды "" "#dig @ ns0.xname.org dddddd.eu mx" "" "и" "#dig @ ns0.dddddd.eu dddddd.eu mx" "" "возвращают разные ответы! Серверы NS-серверов не видят мою MX-запись mail2.dddddd.eu. Зачем? Пожалуйста, помогите мне!

#dig @ ns0.xname.org dddddd.eu mx
