Spammers Use Non Delivery Reports To Reach Inboxes

Our Comments

This problem affects mostly fat clients (i.e. the likes of Outlook) where filtering occurs either at the service provider or within the company's mail system. Ironically, web-based services like Gmail and Yahoo Mail, which are focused on consumers rather than businesses, tend to be more proactive simply because they have the resources and can roll out radical changes very quickly.
