The Difficulties of Tracing Spam Email
Dan Boneh · 2004
At the FTC staff’s request, I prepared this report to discuss the specific difficulties of identifying a spammer by following the electronic trail embedded in spam email. This report will not discuss any investigative technique other than electronic tracing — it will not, for example, discuss tracking spammers based on insider information, spam body analysis, or other investigative techniques that do not involve electronic tracing.
