Abstract
Dynamic directory harvest attack detection and mitigation system is accomplished by altering the logic surrounding how a receiving email server enforces its email delivery rules. The email server's assumed response to received emails is changed when it is determined that the server is under attack, thereby foiling the unauthorized acquisition of valid email addresses and other information retained by the email server.
