Hello

I have internal AD domain  internal.test-networking.com  and external domain test-networking.com purchased on godaddy. On hyper-V machine I installed exchange server 2013, please help me How to configure all necessary dns records internally and on godaddy account, my ISP opened port 25 and it is forwarded to my exchange server

Any help please

Look up "split-brain DNS" or "split DNS" to learn how to best configure networking for Exchange.

Hi shototadumadze, 

Thank you for your question.

When Exchange was installed, we didnt configure the internal DNS record for internal message flow. If we want to send/receive email from external, we should register the following record in godaddy server: 

mail.contoso.com 

autodiscover.contoso.com 

We could refer to the following link:

If there are any questions regarding this issue, please be free to let me know. 

Best Regard, 

Jim

                                           

Hi

externally the DNS records should be created as below

Create MX Record as below and point it to godaddy ISP

Create = test-networking.com to   MX   10   GoDaddyMXrecords

 
Similarly create new DNS CNAME for owa and auto discover on GoDaddy

mail.test-networking.com                      to         CNAME  GodaddyISP
webmail.test-networking.com                to         CNAME  GodaddyISP
autodiscover.test-networking.com         to         CNAME  GodaddyISP
