Abstract

The primary original design goal for email was toprovide best-effort message delivery. Unfortunately, asthe ever increasing uproar over SPAM demonstrates, theexisting email infrastructure is no longer well suited tothe worldwide set of email users - particularly email receivers.Rather than propose yet another band-aid solutionto SPAM, this paper rethinks email from the requirementsperspective, albeit with the constraint of designing a systemsuitable for incremental adoption in the current environment.Our result to this exercise is a policy driven emailservice in which the interests of each principal can be articulatedand accommodated. Our scheme rewards faithfulsenders with better quality of service and discourages misbehavior.Our scheme provides receivers with policy-drivencontrol over whether and how a given message appears inthe recipients mailbox.
