DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an e-mail has been sent by an authenticated person or server. An electronic signature is added to the header of the message by using a private key. When the email message is received, a public key that is available in the global Domain Name System is used to validate who actually sent it and if the content has been edited in any way. The primary job of DKIM is to hinder the widely spread spam and scam emails, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t correspond, you will either not get the email message at all, or you’ll receive it with an alert that most probably it’s not legitimate. It depends on email service providers what exactly will happen with an email which fails to pass the signature check. DKIM will also give you an added layer of security when you communicate with your business allies, for instance, since they can see that all the emails that you exchange are genuine and haven’t been tampered with in the meantime.
DomainKeys Identified Mail in Shared Hosting
When you obtain one of the shared hosting that we offer, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you add to your hosting account, so you will not have to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our NS and MX records (so that the email messages related to this domain will be handled by our cloud platform), a private encryption key will be issued straight away on our email servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses set up using this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target audience and the receivers will be sure that the messages are genuine, because the DKIM feature makes it impossible for unauthorized people to spoof your addresses.
