DomainKeys Identified Mail

DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email using an electronic signature. When DomainKeys Identified Mail is enabled for a certain domain, a public encryption key is published to the global Domain Name System and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the message is received, that signature is checked by the incoming server using the public key. In this way, the recipient can easily discern if the email message is genuine or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email message has been edited in the meantime as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or deleted. This email authentication system will strengthen your email safety, since you can verify the genuineness of the important emails that you receive and your associates can do the exact same thing with the emails that you send them. Based on the given mail service provider’s adopted policies, an email that fails the test may be deleted or may end up in the recipient’s inbox with a warning flag.
