DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email by using a digital signature. When DomainKeys Identified Mail is enabled for a particular domain, a public key is published to the global DNS system and a private one is kept on the mail server. If a new email is sent, a signature is generated using the private key and when the message is delivered, that signature is validated by the incoming POP3/IMAP email server using the public key. Thus, the receiver can easily recognize if the email is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered messages are identical and that nothing has been added or erased. This validation system will heighten your email security, since you can confirm the authenticity of the important email messages that you get and your colleagues can do likewise with the emails that you send them. Based on the given mail service provider’s adopted policies, a message that fails the check may be deleted or may be delivered to the recipient’s inbox with a warning sign.
