Having worked in Banking most of my life - it is common to receive these sorts of emails (known as Phishing) - ignore them - they are all pathetic traps for the trusting among us.
For the information of anyone else - if you get any of these unsolicitored emails - usually from Nigeria but increasingly from other African sources asking you to open an account for them to deposit a recent windfall (and for which you will be amply rewarded) - ignore and delete immediately.
Sounds obvious doesn't it - but there's always a victim out there it seems.
