Need Some Help: Cloudron.io message

Hello,

I got this in the errors of the Cloudron.io setup in my home server with Ubuntu 20.04 LTS and I am wondering what it means since I cannot get the email server portion running. The only line I understand is the last one and am working on clearing that up.

Most of that has nothing to do with Cloudflare, but it appears you’re trying to run a mail server over your local ISP, which is usually not permitted.

Cloudflare does not handle PTR records for your local network.

The TXT records messages are pretty self explanatory. Whatever you have set in your authoritative DNS is not correct.
