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 specific domain, a public cryptographic key is published to the global DNS database and a private one is stored on the mail server. When a new message is sent, a signature is generated using the private key and when the email is delivered, that signature is authenticated by the POP3/IMAP email server using the public key. Thus, the recipient can easily recognize if the message is legitimate or if the sender’s address has been spoofed. A mismatch will occur if the content of the email has been altered on its way as well, so DKIM can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or removed. This authentication system will heighten your email security, as you can verify the legitimacy of the important emails that you get and your associates can do the same with the email messages that you send them. Based on the given email service provider’s adopted policy, a message that fails to pass the test may be deleted or may emerge in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Web Hosting

If you host a domain in a cloud web hosting account with our company, all the required records for using the DomainKeys Identified Mail option will be created by default. This will happen as soon as you add the domain name in , on the condition that the domain also uses our NS records. A private key will be created on our email servers, whereas a public key will be published to the DNS database automatically using the TXT record. In this way, you will not have to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your messages will be sent to any audience without being discarded and no one will be able to send emails forging your email addresses. The latter is rather important if the essence of your web presence suggests sending regular newsletters or offers via email to prospective and current clients.
