I am trying to use ovh email exchange service which requires cname domain verification.
My dns is managed by cludflare. Even I add the required record ovh can’t authenticate it.
I have tried on domain which is managed by me and it works. I have asked the ovh and they told me that the record is not propagated correctly. The record is something like dxsde-zzt.mycomain.com cname ovh.com
Make sure the record is set to and not .
Thank you very much.
It solved my problem.
