SSL Certificate invalid on DNS Only records
I have a STMP server I am trying to set up using MTA-STS and it requires a cname record that points to the origin server. It also requires it to be over SSL so I need the certificate to be valid. With DNS only that seems to not work.

What certificate do you have on your origin server?
The certificate signed by cloudflare
From SSL/TLS>Origin Server
It’s a self signed cert so not publicly trusted. You’ll need something like a let’s encrypt cert
Wait
I actually do have a LE cert
I just use Cloudflare for my forum
Should I use Lets Encrypt for both and will that work on an apache server?
Yeah let’s encrypt for both. The origin cert is only good between origin and Cloudflare
