Hi,
As rightly said by Mr. R.Ponraj, it is a part of Nigerian syndicate. This mails are in circular from many years. They usually ask for your CV to be uploaded, from there they get your contact details, apart from that they ask you to furnish your bank a/c details. Infact the crime branch had caught some Nigerians who were behind this, but it is difficult to stop them completely as they keep on creating new ID's. I receive such mail almost twice or thrice in a week, now I have marked it as spam. Please dont bother to reply as they can misuse your details, so best thing to do is just delete it.
Apart from this some of them send SMS, stating you have won a lottery asking for your bank account details, so please see that you just delete it. Also tell your family members to ignore such SMS, children may get exited about such huge amount and give the confidential details, so also make them aware.
Regards
Anita
