Does yahoo have international lotto and request personal info?

I received an email from OVERSEAS CLAIMS UNIT, Yahoo! Lottery Fiduciary, Contact Person: Mr Mark Wakefield, Email: onlinefiduciarry@myway.com stating that I had won a large sum. It also requested alot of personal information that I'm not really comfortable giving if I'm not sure that this is a true site. I clicked on a link within the email that said yahoo lotto and it took me to a yahoo site, however I was just wondering if it was truely legit. If anyone is familiar with yahoo lotto or knows a legitimate yahoo email address that I can contact to get some answers I'd really appreciate it.... Thanks!! :-)
