Domain keys Identified Mail (DKIM) for Spam Control

Free registration required

Executive Summary

SPAM (UBE) is email sent to groups of recipients who have not requested it or have "Opted out" of group email subscriptions and continue to receive email from the sender. So the authors devise a DKIM (Domain Key Identified Mail), which is a domain-level authentication framework for email using public-key cryptography and key server technology to permit verification of the source and contents of messages by either Mail Transfer Agents (MTAs) or Mail User Agents (MUAs). The ultimate goal of this framework is to permit a signing domain to assert responsibility for a message, thus protecting message signer identity and the integrity of the messages they convey while retaining the functionality of Internet email as it is known today.
