Hey people,

This is my first post here, i will try to explain the problem i have as best i can.

I have recently setup a new server for a company, now everything works as intended, It is a 2008r2 Install running ADDS, DNS, DHCP and Remote services (all they use it for is thier Point of sale program)

Now after installing they can no longer see thier mail server (which is hosted offsite with a hosting company), i can ping it from anywhere else i try except from thier main office.

the domain on the server is the same as thier mail server name. so their domain is formatted as such "ABCD.com.au" and thier main server name is "mail.ABCD.com.au"

I think that when the computers are trying to get to thier mail domain it is hitting the servers DNS and the server isnt pushing it to the net where thier mail is but keeping it to itself and basically saying "this doesnt exsist here"

Does anyone know how i can tell the server that its supposed to push it to the net and not look internally ?

Hope soome of this made sense. if not post and i will try to clear up anything!

Thanks in advanced peoples.

Never mind, fixed it.

For anyone with this issue, had to creat an A record to point it to the correct external IP instead of looking internall on its own domain

The A record is required for the external address. There should also be an MX record which is used specifically for mail servers to designate the FQDN.

Edit: for correctness
