DomainKeys Identified Mail, or DKIM, is a system for confirming the authenticity of an email message by using an electronic signature. When DKIM is enabled for a given domain, a public encryption key is published to the global Domain Name System and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the email message is received, the signature is verified by the incoming mail server using the public key. In this way, the receiver can easily discern if the message is authentic or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or erased. This validation system will increase your email safety, as you can validate the authenticity of the important emails that you receive and your partners can do likewise with the messages that you send them. Based on the particular email service provider’s policy, an email message that fails the test may be erased or may enter the recipient’s inbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

If you buy any of the cloud hosting that we offer, the DomainKeys Identified Mail feature will be enabled by default for any domain name that you add to your shard hosting account, so you won’t have to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the emails related to this domain name will be handled by our cloud hosting platform), a private encryption key will be created straight away on our mail servers and a TXT record with a public key will be sent to the global Domain Name System. All email addresses created with this domain name will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that the messages are authentic, since the DomainKeys Identified Mail functionality makes it impossible for unsolicited parties to spoof your addresses.
