DKIM is definitively a must have for gmail.

If Hotmail is doing that to your messages, you're in a quite bad 
posture. That's their way to tell you "we don't like what you're sending 
at all".

Did you consider hiring deliverability consultants? I'm afraid there is 
no magical way to reach inbox without a audit of your process and systems.
