Anyone know anything about an internet lottery called Powerball?

i received an email from a company called Powerball who claim to have done a lottery on the internet using peoples email addresses!they say i have won 1million euros.i know these sort of things are usually con-men,but this one does seem differerent and more genuine than others.they want some personal information from me,but they are not asking for bank details,they say i can have the money sent by transfer or delivered by courier,so if i get it by courier,how can they rip me off?
