Recently, our business mail server started to get "deferred" log messages for mail sent to my customers on another ISP's mail service. To cut a long story short, the delegation record for my static IP address is resolving to:
These name servers do not exist.
Can someone please help me to escalate the issue to get the problem fixed?
Thanks for sending me the details, this has been relayed to our Team. I will keep an eye on this and I'll provide you updates whenever it becomes available.
I have sent you a PM with all the details.
