Howdy!

So i'm trying to add my custom domain for  with the mail server. I have 100% control of my DNS and have tried every single option (TXT, CNAME, and even HTML) multiple times, ensuring i did it properly, to no luck. I get the same error message every time:

My HTML verification is right here.

Sorry if i posted this in the wrong place or worded it funny, I've never asked for help on this form.
