I just build two servers 2012. One is the DC and one is the Exchange 2013
On the DC I have two OU. One is for let's say users on town 1 and the other OU is for users on town 2. Emails for users on town 1 is email@example.com and users for town 2 is firstname.lastname@example.org
Town 1 users are fully in Exchange and the MX records point to the Exchange server.
No problem here. Users on town 2 still on an pop 3 external email provider until we move them to the exchange server two weeks from now. I want to keep the users accounts and the emails on the server until then but I want the internal users from town 1 to be able to send emails to town 2 to the Pop 3 emails that is outside and not to the exchange server.
At the moment if an email is send from any users internally to users on town 2 it will go to exchange not to pop3.
So I create a new zone call domaintown2.com on the internal dns and on that zone I create the mx records of the pop3 server but I still receive all the emails on the exchange server. What do I miss?
I already flash the DNS
