Oh ! Sorry, my mistake.
You get those domain when you run host on your computer but didn't see
them on the dump I've copied here ?

I got it now by simply doing the same operation you did.
I notice something that sound strange...
When I configured my domain, I've said the mail exchange (MX) is
mail.cyrania.com and when I run host -t mx this give me something
different. And the answer start with a underscore like you have noticed.

I'll switch back to using the "plain" DNS offered by my hosting provider
and see what it give out.

I really don't have real need for Cloudflare, except some expectation it
would give a bit more speed to my server thru the work on automatic caching.

I'll send you a message when it's done.
I got a bit of work to do now, will do so later today.
