Hi,
I have installed exchange 2010 on Windows 2008 r2. I installed edge transport server role. My problem is that I have configured my AD as testdomain.local and my internet domain is testdomain.in.

Now I have configured exchange to accept mails for testdomain.in domain (i.e authoritative) and also configured the corresponding email policy to add the email address for the same domains also. Now when I send mail from outside like yahoo and gmail they hit my edge server but will lie in queue saying that 451 4.4.0 DNS query failed. I also tried to make my testdomain.in default authoritative domain. But still there is problem.

How can I resolve this issue.

Thanks.
