I have one domain on OVH. I use with this domain CloudFlare.
On my domain I need only one email, that I use only for forward. On OVH the MX record for only forward email is: redirect.ovh.net
I put this MX value in the CloudFlare, but when I send an email, is rejected:
"Delivery to the following recipient failed permanently:
Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the server >for the recipient domain domain.com by redirect.ovh.net.
The error that the other server returned was: 553 sorry, that domain isn't allowed to be relayed thru this MTA (#5.7.1)"
But if in OVH I activate the free basic hosting (start1m) with is own MX records (mx1.ovh.net and mx2.ovh.net) the email forward work !
The problem is caused because OVH doen't recognize CloudFlare name server ? How can I resolve this error ?
