DomainKeys Identified Mail, or DKIM, is a method for verifying the authenticity of an email message using a digital signature. When DomainKeys Identified Mail 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. When a new email message is sent, a signature is generated using the private key and when the message is delivered, that signature is ‘scanned’ by the POP3/IMAP mail server using the public key. Thus, the recipient can easily distinguish if the email is genuine or if the sender’s address has been forged. A mismatch will appear if the content of the email message has been changed on its way as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This validation system will enhance your email safety, as you can confirm the legitimacy of the important email messages that you receive and your partners can do the same with the email messages that you send them. Based on the given mail service provider’s adopted policies, an email that fails the examination may be deleted or may emerge in the receiver’s mailbox with a warning flag.

DomainKeys Identified Mail in Shared Hosting

When you order any of the shared plans that we offer, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you add to your shared account, so you will not have to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS resource records (so that the emails associated with this domain will be handled by our cloud platform), a private encryption key will be issued straight away on our mail servers and a TXT resource record with a public key will be sent to the global DNS database. All email addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as regular newsletters, they will reach their target destination and the recipients will be sure that they are genuine, since the DKIM functionality makes it impossible for unauthorized parties to forge your email addresses.
