Lol Mr.Grim...
I've been receiving hundreds of such emails since 2003...
It's a relatively new scam they are pulling, with several reasons that they want to transfer money to you.
If you agree, they ask you for bank papers, ID photocopy, etc...to make it seem convincing. They also have some fake websites that are supposedly the bank ones...
The point of all this, is that they ask you to send them in advance about 100-300 $ , depending on the scammer, which will be the only amount they need to arrange the bank transfer, cause the million dollars are locked and they cannot pull not a penny out of them, supposedly.
So to conclude, this scam is only to take from you (and from lots of others too) about 100-300$ . That's it, you're the victim if you do so
