I need to redirect my MX record to our new Exchange Server but there is things that I don't get ...
My domain name his provided by OVH and my hosting is at 2MHOST. So in my OVH control panel the DNS (NS1 and NS2) are pointing to 2MHOST servers.
But both of them give me possibility to edit MX record, I can do it by OVH (Manager -> DNS Zone) or by 2MHOST (via cPanel).
Who has the priority ??
The company who have installed us the Exchange server told me that I needed to create a subdomain that point to our server IP and then change the MX record to that subdomain and also ask my ISP to create a reverse DNS to that subdomain.
I am a bit lost of what and where I am supposed to do the stuff.
I have activated DNS zone from OVH right now, because there were not active and it look like it's the only way to create a subdomain redirecting to our IP (ZONE A).
I can't nslookup that subdomain, maybe it take a little time ?
Now I need to change the MX record from my Host or from OVH (DNS zone) ?
Thank if someone can help me out a little bit.
