It's just unconditioned reaction. I also post this message to some forums, you know. I am affaird that hotmail.com / outlook.com and all microsoft email domains are configured to block emails from new/fresh domain and newly created email accounts, which have quite low reputation. I read that they created own system that filter "spam" emails. Of course it filters good emails. Even Google is not that hardcore.
