If you register a domain with Cloudflare or Route 53, and that service goes down, do your records stay active in the DNS servers? What if the DNS servers go down, I know a lot of people use 8.8.8.8, so if Google's server goes down, then DNS fails?...
If the DNS server for your Domain goes down the records should still be saved in all the other DNS servers around the world. They will stay the same as they were before you domain's DNS server wen't down. While your DNS server is down you won't be able to change where the Domain points. While your registration server is down you will not be able to transfer or sell your domain.
I've never really understood the whole TTL thing. Will the domain essentially point to nothing if the TTL runs out while the DNS server is down or will it default to older record?
FIRST, you need a host that lets you set PTR records for your IP. Check out Mailcow if you want to host your own server. It automates the security process and generates all the DNS records you need for your server to send email that won't be flagged as spam.
Once your server is set up you can test it with https://www.mail-tester.com/. If you can get a score of 10 you will be golden.
