DNS & email nightmare
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.
