I'm searching for a dynamic DNS Solution for a mail server. My client have a Exchange 2013 farm with 2 internet Access.
Actually, MX high availability is OK (MX 10 point to one public ip adress & MX 20 point to the second one).
I want to find a solution to automate the DNS change of the URL "webmail.client.com" to point to the active internet line.
My firewall i actually able to switch to the second line if first line become unavailable.
I found one solution : install a dyndns/no-ip system on the exchange server to announce to DynDNS service the actual public IP but i'm searching for a system which is able to check (for exemple) the availability of the webmail and to point to the good IP address.
