I am creating emails and succeeded with
administrator[at]kili-tanzanitesafaris.com
tours[at]kili-tanzanitesafaris.com

But when I create infoat]kili-tanzanitesafaris.com i got an error
"AA101:Oops! Something went wrong. Try again later"

I guess I have a problem with info, other ids created very well
Please help
If possible please delete or let me know is infoat]kili-tanzanitesafaris.com has been listed or created
