Yhea, it's suspicious why they doing it.
I mean, that's only makes it even more obvious that is fake.

Don't know but started to believe Hotmail might be responsible for some of these e-mails in purpose of making researches in how users behave and treat this kind of material.
That wouldn't surprise myself if that's a fact as they somewhere have to get this information in understand how to develop the service in give appropriate security and protection.
It's only because they want to know how stupid people is
