  text: Spam e-mails have become a serious technological and economic problem. Up
    to now, by deploying complementary anti-spam measures, we have been reasonably
    able to withstand spam e-mails and use the Internet for regular communication.
    However, if we are to avert the danger of losing the Internet e-mail service in
    its capacity as a valuable, free and worldwide medium of open communication, anti-spam
    activities should be performed more systematically than is currently the case
    regarding the mainly heuristic, anti-spam measures in place. A formal framework,
    within which the existing delivery routes that a spam e-mail may take, and anti-spam
    measures and their effectiveness can be investigated, will perhaps encourage a
    shift in methodology and pave the way for new, holistic anti-spam measures. This
    paper presents a model of the Internet e-mail infrastructure as a directed graph
    and a deterministic finite automaton and draws on automata theory to formally
    derive the spam delivery routes. The most important anti-spam measures are then
    described. Methods controlling only specific delivery routes are evaluated in
    terms of how effectively they cover the modeled e-mail infrastructure; methods
    operating independently of any particular routes receive a more general assessment.
