I've recive this email. I'm still in the proccess of seeing if it actually
came from .net services,

But it wouldnt surprise me, there are a few known holes in the MSN login path
that allows someone to take control over another's MSN account. Or even just
spoof the victims account. Ethier way, Its probably some retarded buffer
overflow in the msn client. Kinda like the cute buffer overflow in msn 6 :)
