Understanding Forgery Properties of Spam Delivery Paths
Source: Florida State University
It is well known that spammers can forge the header of an email, in particular, the trace information carried in the Received: fields, as an attempt to hide the true origin of the email. Despite its critical importance for spam control and holding accountable the true originators of spam, there has been no systematic study on the forgery behavior of spammers. In this paper, the authors provide the first comprehensive study on the Received: header fields of spam emails to investigate, among others, to what degree spammers can and do forge the trace information of spam emails.
