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. -- Polyna-Maude R.-Summerside -Be smart, Be wise, Support opensource development
