I have been receiving emails from someone saying that they have an enormous sum of money and that all I need t

I have been receiving emails from a few people most from Nigeria claiming to have at lease 10 million usd that will come dicectly to me and all I have to do is give them specefic information relating to me just general like address phone numbers and in some cases send a copy of my i.d to them immediately so that they can send the funds via courier who supposedly will move down here and deliver the funds to me directly. I am very suspicious about these claims but would like to know if this is a really bad scam that a lot of people may be falling for. Please let me know of anything you may know about this matter ASAP.
