The email was probably sent by a bot or a mass mailer from someone sitting in a free wifi cafe or through a proxy server. You can maybe find out the country, city if you're lucky, the email originated in by reading the email headers, but that's as close as you can get to "fucking with them" I'll narrow down (slightly) the possibilities for you by region: Africa and South America. They get smarter every year, pretty soon they'll be texting you on your phone.
