DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email by using a digital signature. When DKIM is activated for a certain domain name, a public encryption key is published to the global DNS database 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 message is delivered, the signature is validated by the incoming email server using the public key. In this way, the recipient can easily distinguish if the message is authentic or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email has been modified 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, since you can confirm the genuineness of the important emails that you get and your partners can do likewise with the email messages that you send them. Based on the particular email service provider’s adopted policies, an email that fails to pass the check may be removed or may appear in the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Cloud Website Hosting

If you obtain any of the Linux cloud website hosting packages that we are offering, the DomainKeys Identified Mail feature will be enabled by default for any domain that you register under your shared web hosting account, so you will not need to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud web hosting platform), a private encryption key will be issued instantly on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All addresses created using this domain name will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target destination and the recipients will be sure that they are legitimate, since the DKIM functionality makes it impossible for unauthorized parties to spoof your e-mail addresses.
