Yahoo SCAM e-mail

Please do not fall into the trap. I don't think it's from Yahoo. Most probably it's from some scumbag who pretends to be a Yahoo official. I've had a lot of emails saying that i won lotteries and so on which i didn't enter in the first place. There are so many scams nowadays so you have to be more careful. One way to find out is to contact Yahoo and ask them about it. But I'm pretty sure it's a scam. Cheers
