Hi. We (bilisimatolyesi com tr and bilisim-atolyesi com tr) can not get any emails from yandex hosted domains (for ex. pulak com which DNS services is also on Cloudflare). The return error is like this: Diagnostic-Code: X-Yandex; Host or domain name not found. Name service error for name=webmail cozumeposta com type=AAAA: Host not found.
I’d contacted Yandex support and they forwarded us to Cloudflare Support. Need help asap. Kind regards.
