I have been working on implementing RFC2136 DNS UPDATE instead, since I actually need that for myself when I ran into wanting to set up Let's Encrypt with Home Assistant, and it only supports some pre-selected "big guys" or the RFC2136 method for DNS challenge.

CAA records are now available in Primary DNS.

Probably too late for some people who gave up waiting, I know, but nevertheless it's done.

It will still reject if it scores higher than the Maximum Allowed Score (set to 20 in your screen shot), so if you want to be sure nothing is rejected you can change the Maximum Allowed Score to something like 100.

It seems that your DNS is messed up, as you may have guessed. Unfortunately there's nothing we can do to fix that since we aren't hosting your DNS. Have you contacted your hosting service and registrar and informed them of the issue? If you're having problems with your current DNS host you could try...

The short answer is you don't. Mail servers of the world expect port 25.

We have our SMTP Redirection service to accept mail, queue it, then send it to you on a different port when port 25 is blocked.

Also keep in mind that IP addresses can become blocked if they are associated with too many failed username/password attempts.
