Hello everyone.
I do not know much about DNS so I am hoping someone will point me to the right direction.
Basically, last week, all emails sent from our server to a particular domain xyz.com came back as undeliverable.
After a lot of going back and forth, the issue was that
our ISP handles DNS for us, and they had been hosting xyz.com last year. Since last year, xyz.com switched to a different ISP, so their MX records changed.
In other words, my ISP resolved xyz.com to old-IP.
I solved this particular problem by creating a fwd lookup zone on my local server and manually pointing all requests to xyz.com to the right IP address.
Someone told me that I should be able to use smth called root servers and skip our ISP entirely for DNS requests.
Does anyone know how to do that?
Thanks,
kopja
