Hi There, I used to use shared hosting before and I created a google app account and I configured DNS records on shared hosting's contol panel according to google dns documentations.

Everything was working until I switched to dedicated server. First I added DNS role to my new server and I configured whole DNS and NS stuff.

I have mail address that mail.domain.com that was redirecting to google app email before. Rightnow, It's not possible to access to mail.domain.com addres from somewhere. But I'm accessing from a few point which located some computer on different network.

I stacked in this problem. Please, see the below screen shots

I checked on DNSStuff.com,everything is green.

Also, I checked on InteliWiz, it seems correct

And, Here is the my DNS records.

I was accessing to my mail.domain.com address from everywhere, Now, I cannot access to mails from many places since 3 week.

Where is the my mistake ? Any help would be appriciated.
