DomainKeys Identified Mail, or DKIM, is a method for verifying the genuineness of an email using an electronic signature. When DKIM is enabled for a particular domain name, a public cryptographic key is published to the global DNS system and a private one is stored on the mail server. If a new email message is sent, a signature is generated using the private key and when the message is delivered, that signature is validated by the incoming mail server using the public key. In this way, the recipient can easily recognize if the message is genuine or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been modified in the meantime as well, so DKIM can also be used to make sure that the sent and the received emails are identical and that nothing has been added or erased. This email authentication system will increase your email security, as you can validate the legitimacy of the important email messages that you receive and your associates can do the exact same thing with the emails that you send them. Based on the particular email service provider’s policies, an email message that fails to pass the check may be erased or may enter the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Cloud Hosting

In case you host a domain in a cloud hosting account with our company, all the needed records for using the DomainKeys Identified Mail option will be set up by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, on the condition that it also uses our NS records. A private cryptographic key will be created on our email servers, while a public key will be sent to the global Domain Name System automatically by using the TXT resource record. In this way, you won’t need to do anything manually and you will be able to make use of all the benefits of this email authentication system – your email messages will be delivered to any destination without being rejected and no one will be able to send out email messages faking your email addresses. The latter is quite important if the type of your web presence involves sending regular newsletters or offers via email to prospective and existing clients.
