DomainKeys Identified Mail, or DKIM, is a method for verifying the legitimacy of an email message by using an electronic signature. When DKIM is activated for a certain domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the email server. When a new email message is sent, a signature is issued using the private key and when the email is delivered, the signature is checked by the incoming mail server using the public key. Thus, the recipient can easily know if the email message is legitimate or if the sender’s address has been forged. A mismatch will appear if the content of the email has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or deleted. This validation system will increase your email safety, as you can validate the authenticity of the important emails that you receive and your associates can do likewise with the email messages that you send them. Depending on the given email provider’s adopted policy, an email that fails the check may be removed or may end up in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain in a cloud hosting account with our company, all the compulsory records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, provided that the domain also uses our NS records. A private encryption key will be created on our mail servers, whereas a public key will be sent to the DNS system automatically using the TXT record. Thus, you won’t have to do anything manually and you will be able to make use of all the benefits of this authentication system – your emails will reach any destination without being denied and nobody will be able to send out email messages forging your addresses. The latter is rather important if the type of your worldwide web presence suggests sending periodic newsletters or offers via email to potential and existing clients.
