DomainKeys Identified Mail

DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email using an electronic signature. When DomainKeys Identified Mail is enabled for a given domain name, a public cryptographic key is published to the global DNS system and a private one is stored on the mail server. When a new email is sent, a signature is generated using the private key and when the email message is received, the signature is ‘scanned’ by the POP3/IMAP email server using the public key. In this way, the recipient can easily tell if the message is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered emails are identical and that nothing has been added or removed. This authentication system will enhance your email safety, as you can verify the legitimacy of the important emails that you get 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 policy, an email message that fails the examination may be erased or may be delivered to the receiver’s inbox with a warning alert.
