Recently I had to move my email server from my home office to a VPS provider. In doing this problems appeared that I had not had before. First all I changed was the IPV4 address of the mail server to the new VPS address. Then wanting to do all I can to secure the new email server software Mailcow. I added new DNS records for DKIM, SPF and DMARC & attempted to add the PTR record. This where things got weird. Coludflares documentation instructs to add a site. I had to dig to understand that it should say domain because to Cloudflare they are the same. OK, I did that & I was instructed to add two DNS records but I don't own the in-addr.arpa domain so I added them to my domain in addition to the other two Cloudflare DNS servers. Thing seemed to work for several days maybe a week but now I received an email from Cloudflare below & DNS resolution for my domain fails. Any help would be appreciated. Thanks.
Hello,
The nameservers for [EXAMPLE].com no longer point to Cloudflare. They now point to:
matt.ns.cloudflare.com
coraline.ns.cloudflare.com
veda.ns.cloudflare.com
yisroel.ns.cloudflare.com
[not set]This change means that [EXAMPLE].com is no longer using Cloudflare and will not receive the benefits of Cloudflare's security and performance services. Your DNS records will be completely removed from Cloudflare's system in 7 days.
If the nameserver change was in error, reactivate your domain by pointing your nameservers back to:
matt.ns.cloudflare.com
veda.ns.cloudflare.comOnce you have completed this change, click the “Check Nameservers” button in your Cloudflare dashboard to ensure your domain stays active on Cloudflare.
You can take these steps by visiting the Cloudflare dash at the link below:
