I setup two domains for testing, and I am wondering if I might have problems with the way I setup the domain names. Here is an example. For domain 1, I called it MyTestDomain and I did not create a .local. Instead, the domain it is MyTestDomain.net.
I also created another domain. It is called MyTestDomain.local.
So, I have one domain that is MyTestDomain.net and another that is MyTestDomain.local.
By the way, the actual domain name is different but I am using MyTestDomain for the example.
If it is OK to have two domains like this, what will happen if I install Exchange server on both domains? The domain called MyTestDomain.local will be able to receive incoming mail from MyTestDomain.com.
In the end, one test domain will be able to receive messages from MyTestDomain.net and the other domain will be able to receive messages from MyTestDomain.com.
Should I start over and have two completely different domain names, or is what I have setup good?
