DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email using a digital signature. When DomainKeys Identified Mail is enabled for a given domain name, a public encryption key is published to the global Domain Name System and a private one is stored on the email server. If a new message is sent, a signature is issued using the private key and when the message is received, the signature is authenticated by the incoming server using the public key. In this way, the recipient can easily tell if the email is genuine or if the sender’s address has been forged. A discrepancy will occur if the content of the email message has been edited on its way as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or removed. This authentication system will heighten your email safety, as you can verify the authenticity of the important email messages that you receive and your partners can do likewise with the messages that you send them. Depending on the given email provider’s adopted policy, an email message that fails the check may be erased or may appear in the recipient’s mailbox with a warning symbol.

DomainKeys Identified Mail in Web Hosting

If you order any of the web hosting plans that we offer, the DomainKeys Identified Mail option will be activated by default for any domain name that you register under your shared account, so you won’t need to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS resource records (so that the emails related to this domain name will be handled by our cloud platform), a private cryptographic key will be created straight away on our mail servers and a TXT record with a public key will be sent to the Domain Name System. All addresses created using this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that the messages are legitimate, as the DKIM feature makes it impossible for unsolicited persons to spoof your addresses.
