Hi, my domains .com and others can only be resolved by some isps in portugal, i cant even make a traceroute because just dont exist in zon,netcabo,vodafone,etc. But the question is why "master" isp´s in portugal Ptprime,telepac,tmn(3g), can see my domains and the others dont. That causes my client e-mails be rejected because their domains doenst exists. I make traceroutes even from Australia and my domains exist. I made the test changing the tcp/ip dns server in my connection, to use diferent isp´s. Does anywone has a clue ? Thanks.
