Ini masalah DNS resolver yang tidak bisa resolve dengan baik karena DNS
recordnya panjang/banyak.

Apakah ada firewall didepan MDaemon dengan Internet?
Jika ya, pastikan outbound tcp port 53 di open/allow.
Serta EDNS0 di MDaemon DNS resolver diaktifkan.

[x] Use EDNS0 (Extension Mechanisms for DNS)
