DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email by using an e-signature. When DKIM is activated for a given domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the mail server. If a new email is sent, a signature is generated using the private key and when the email message is received, that signature is authenticated by the incoming POP3/IMAP mail server using the public key. Thus, the receiver can easily know 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 has been changed on its way as well, so DKIM can also be used to make sure that the sent and the delivered emails are identical and that nothing has been attached or deleted. This email validation system will strengthen your email safety, as you can validate the authenticity of the important emails that you receive and your partners can do the exact same thing with the email messages that you send them. Based on the particular email provider’s policies, an email that fails the check may be deleted or may reach the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail feature is enabled by default for all domains that are hosted in a cloud hosting account on our cloud servers, so you won’t have to do anything on your end to turn it on. The sole requirement is that the particular domain name should be hosted in an account on our platform using our NS and MX resource records, so that the emails will go through our mail servers. The private key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you won’t need to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail email validation system will permit you to send out trustable e-mail messages, so if you’re sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, whereas unsolicited third parties won’t be able to forge your email addresses.
