I'm not disputing it.
I'm also not saying it is, or it isn't, because I don't know.
What I am saying is, what I do know is, that you probably can't open a Sev A DCR ticket with HotMail, and neither can I.

That, and … it would seem there may be two things broken.
And that fixing the MX "recursion" may re-cloak the apparent bug in HotMail.

Which one can be fixed faster?
