DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email by using a digital signature. When DKIM is enabled for a particular domain name, a public key is published to the global DNS database and a private one is stored on the mail server. If a new email is sent, a signature is issued using the private key and when the email is delivered, the signature is verified by the incoming server using the public key. Thus, the recipient can easily distinguish if the email is legitimate or if the sender’s email address has been forged. A discrepancy will appear if the content of the email message has been edited in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered messages are identical and that nothing has been attached or erased. This email authentication system will heighten your email security, as you can verify the legitimacy of the important emails that you receive and your associates can do the same with the messages that you send them. Based on the given email service provider’s policy, an email message that fails the check may be erased or may reach the receiver’s mailbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail feature is pre-activated for all domain names that are hosted in a cloud hosting account on our cloud platform, so you won’t need to do anything yourself to turn it on. The sole requirement is that the particular domain name should be hosted in an account on our platform using our MX and NS resource records, so that the emails will go through our mail servers. The private cryptographic key will be generated on the server and the TXT resource record, which includes the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to enable this feature. The DKIM validation system will enable you to send out trustable e-mails, so if you are sending offers or a newsletter to clients, for instance, your emails will always reach their target viewers, whereas unsolicited 3rd parties will not be able to spoof your email addresses.
