My host  response
It seems like servidor.xxxxx.xxx is not resolving to xx.xx.xxx.11, As advised yesterday, you need to login to Cloudflare and create the A records.


But i use freeDNS?

First part, blacklisting has nothing to do with CWP. That's because part of the network where your ip is hosted (same hosting/service provider) is on Hotmail's block/black list.

If your IP wasn't used for spam you can manually fill this online form to delist just your server IP address: https://support.live.com/eform.aspx?productKey=edfsmsbl3&ct=eformts&wa=wsignin1.0
Otherwise you have to contact your hosting/service provider and paste them this mail response you've got.


Second part, you have to set server hostname, it has to be a subdomain. Then rebuild mail server.
Be sure your subdomain is pointed to server IP address directly using A record on Cloudflare, you can't use Cloudflare Proxy for this, that orange cloud has to be gray for this subdomain. So your IP address has to be exposed by hostname (subdomain used for hostname), hostname can't be behind proxy.
