DNS resolver yang jadi rujukan MDaemon bermasalah atau super sibuk
sehingga lambat responsenya.
DNS resolver yang Anda pakai itu milik nawala.org hanya cocok untuk
rujukan proxy server bukan mail server.

Diganti saja DNS resolvernya dengan public DNS server yang cepat.

[ ] Use Windows DNS servers

DNS servers : 209.244.0.3 8.8.8.8 209.244.0.4 8.8.4.4

yang kedua, jangan pakai fake IP (IP palsu) di MDaemon.
IP 136.68.95.1 milik Ford Motor Company di Amerika sana.

untuk LAN disarankan pakai private IP agar terhindar dari serangan
(attack) dari internet.
