Coba kalau pakai DNSnya APJII (203.119.13.77/203.119.13.78), barangkali diperkenankan oleh ISP.

Test dulu dari Windows dimana terinstall MDaemon.


c:\ nslookup -q=a plant.proswealindomax.com 203.119.13.77

dan

nslookup -q=a plant.proswealindomax.com 203.119.13.78

hasil yang diharapkan mirip ini

$ nslookup -q=a plant.proswealindomax.com 203.119.13.77
