DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email using a digital signature. When DKIM is enabled for a specific domain, a public cryptographic key is published to the global Domain Name System and a private one is stored on the mail server. If a new email is sent, a signature is generated using the private key and when the message is delivered, the signature is ‘scanned’ by the incoming email 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 message has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been attached or deleted. This authentication system will enhance your email safety, as you can validate the legitimacy of the important email messages that you get and your colleagues can do likewise with the email messages that you send them. Depending on the given mail service provider’s adopted policy, an email message that fails the examination may be erased or may end up in the recipient’s mailbox with a warning notification.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail functionality is pre-activated for all domains that are hosted in a website hosting account on our cloud website hosting platform, so you will not have to do anything yourself to enable it. The sole condition is that the particular domain should be hosted in a hosting account on our end using our MX and NS resource records, so that the e-mails will go through our email servers. The private encryption 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 activate this option. The DKIM authentication system will allow you to send out credible emails, so if you are sending a newsletter or offers to clients, for example, your email messages will always reach their target audience, whereas unsolicited 3rd parties will not be able to forge your email addresses.
