There has been recent surge in money laundering schemes advertising themselves as legitimate business via spam.

The scam represents electronic payment services, and normally interface with countries where prosecution is hard or impossible.

For example, INTERAC Email transfer, the Canadian direct debit and email transfer service, has a FAQ entry for email money transfer agent job, and another about email fraud/phishing.

Similarly, Paypal has a question in their FAQ about phishing, and a whole "security center" as well.
