They don't even give you a bounce back email? Just /dev/null with no feedback?
Yep. Maybe it's too costly to temporarily store all that junk e-mail for millions of Hotmail users so they just delete it instead.
Would it help if we @PushoverApp users with accounts there set up email notifications and then individually griped to Outlook/Hotmail support?
With all the Horrorstories about misbehavior of Ms Mailserver I don't consider them a Mailprovider. I couldn't care less if a mail gets eaten by them or not.
