I’m having trouble setting up delegation of a subdomain in order to set up a dedicated IP with our SendInBlue, a mail sending provider we are currently using. I’m following these instructions. We are running our DNS proxied through Cloudflare.
Strangely enough, when I checked for propagation, everything seemed to go fine. But when I came back after a day or two, propagation of the NS records had ‘undone’. What am I doing wrong?
Please note that I’m not very experienced at all in all things DNS related, but eager to learn. Thank you!
