DomainKeys Identified Mail, or DKIM, is a method for verifying the legitimacy of an email message by using an e-signature. When DomainKeys Identified Mail is activated for a specific domain name, a public encryption key is published to the global DNS system and a private one is stored on the email server. When a new email is sent, a signature is issued using the private key and when the message is delivered, the signature is authenticated by the incoming server using the public key. In this way, the recipient can easily recognize if the email message is genuine or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email has been edited on its way 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 removed. This authentication system will enhance your email safety, as you can confirm the genuineness of the important emails that you receive and your associates can do the exact same thing with the email messages that you send them. Depending on the given email provider’s adopted policies, a message that fails to pass the examination may be erased or may be delivered to the receiver’s inbox with a warning symbol.
