Backscatter spam

Because backscatter comes from legitimate mail servers, it can cause special problems. In fact, some security researchers believe that the spammers have been intentionally sending messages that will be bounced back as a way to sneak around spam filters. That's because some mail servers bounce back the original message as part of their notice.
