Abstract:
DomainKeys Identified Mail v2 (DKIM2) permits the owner of a signing
domain to document that they have handled an email message by
associating their domain with the message. This is achieved by
providing a hash value that has been calculated on the current
contents of the message and then applying a cryptographic signature
that covers the hash values and other details about the transmission
of the message. Verification is performed by querying an entry
within the signing domain's DNS space to retrieve an appropriate
public key. As a message is transferred from author to recipient,
systems that alter the body or header fields will provide details of
their changes and calculate new hash values. Further signatures will
be added to provide a "chain" that receivers can validate. This
permits verifiers to identify the nature of changes made by
intermediaries and apply a reputation to the systems that made
changes. DKIM2 also allows recipients to detect when messages have
been unexpectedly "replayed" and will ensure that Delivery Status
Notifications are only sent to entities that were involved in the
transmission of a message.
