DomainKeys Identified Mail.
DKIM lets an organization take responsibility for a message that is in transit. The organization is a handler of the message, either as its originator or as an intermediary. Their reputation is the basis for evaluating whether to trust the message for further handling, such as delivery. It is an encryption authentication method that is used by many ISPs to establish if the email originated from an authorized system and prevents spammers from stealing the identity of legitimate entities.« Back to Glossary Index
