It is unfortunately very common for people to receive emails from
strangers, claiming that they have won a large sum in some
international scheme (or scheme otherwise unknown to the receiver),
inherited something, etc. These are frauds!
Now, I cannot determine if the company you refered to is legitimate or
not, especially not through the very little details you provided.
However, a similar fraud email was posted online at The Original
Gixxer message board
In addition, if you go to the website of Lightwine, you can see that
this site is not active. <www.lightwine.org>.
Thirdly, just think about it - why and how would someone you don't
know send you an email (how would they know your email address), claim
that you won a lottery in which you never participated? Do you really
think that there is such a thing, such as an "International Lottery"?
It is very good that you became suspicious and contacted Google

It should be mentioned, that every person could buy a URL (web site
address) with .org suffix - you don't have to be an organisation. Such
limitations exist on other suffixes (such as .mil for military sites;
.gov for government sites and lately .edu for academic institutions) -
but anyone could have a .org address, including fraudsters.
If you suspect, after reading my answer, that it is a case of fraud,
contact the Internet crime division of your police. If you are
American, you could contact the FTC :
I hope this answered your question.
