"419" Scam – sender domain 163.com:
There are many companies that provide free email services and most people use them for legitimate purposes. However, because there is no charge and hence no need for a verifiable billing address, bank account or credit card, these accounts are fairly anonymous. That and easy access from ubiquitous internet cafes means such accounts are often abused by criminals who send variants of the "419" scam. Most of these emails are sent from Nigeria, Cote d'Ivoire, South Africa and various cities in Europe with West African residents as well as various places in Asia. By reporting the scam accounts to the webmail providers you can usually get them closed.
