DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message using a digital signature. When DomainKeys Identified Mail is enabled for a particular domain name, a public cryptographic key is published to the global Domain Name System and a private one is kept on the mail server. If a new email message is sent, a signature is issued using the private key and when the email is received, the signature is verified by the receiving server using the public key. Thus, the recipient can easily recognize if the email message is legitimate or if the sender’s email address has been forged. A discrepancy will appear if the content of the email has been edited on its way as well, so DKIM can also be used to ensure that the sent and the received email messages are identical and that nothing has been attached or erased. This authentication system will strengthen your email safety, as you can validate the legitimacy of the important emails that you receive and your partners can do likewise with the email messages that you send them. Depending on the particular email service provider’s policy, an email message that fails the test may be removed or may emerge in the receiver’s inbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

When you purchase any of the Linux cloud packages that we offer, the DomainKeys Identified Mail feature will be activated as standard for any domain name that you add to your shared website hosting account, so you will not need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud hosting platform), a private cryptographic key will be generated right away on our mail servers and a TXT resource record with a public key will be sent to the global Domain Name System. All addresses set up using this domain will be protected by DomainKeys Identified Mail, so if you send out emails such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are legitimate, since the DomainKeys Identified Mail functionality makes it impossible for unsolicited individuals to forge your addresses.
