DomainKeys Identified Mail, or DKIM, is a method for confirming the legitimacy of an email message using a digital signature. When DomainKeys Identified Mail is activated for a certain domain, a public encryption key is published to the global DNS system and a private one is kept on the email server. If a new message is sent, a signature is generated using the private key and when the email message is received, that signature is authenticated by the incoming mail server using the public key. In this way, the recipient can easily tell if the email message is genuine or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been changed on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received email messages are identical and that nothing has been attached or removed. This email validation system will boost your email safety, as you can confirm the authenticity of the important emails that you receive and your partners can do the same with the email messages that you send them. Depending on the given email service provider’s policy, an email that fails the test may be deleted or may reach the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Cloud Web Hosting

In case you host a domain in a cloud web hosting account from us, all the needed records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain in , provided that the domain also uses our NS resource records. A private key will be created on our mail servers, while a public key will be sent to the Domain Name System automatically by using the TXT record. In this way, you won’t have to do anything manually and you’ll be able to take full advantage of all the benefits of this validation system – your emails will be delivered to any target destination without being discarded and no one will be able to send email messages faking your addresses. The latter is very important in case the type of your web presence suggests sending out periodic offers or newsletters via email to prospective and current clients.
