DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an e-mail has been sent by an authorized individual or mail server. An e-signature is attached to the email’s header by using a private cryptographic key. When the message is received, a public key that’s available in the global DNS database is used to check who actually sent it and if its content has been edited in some way. The essential function of DKIM is to avert the widespread spam and scam messages, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not get the email at all, or you’ll receive it with a warning notification that most likely it is not authentic. It depends on email service providers what exactly will happen with an email that fails the signature test. DKIM will also give you an added security layer when you communicate with your business associates, for instance, as they can see that all the emails that you exchange are authentic and haven’t been manipulated in the meantime.

DomainKeys Identified Mail in Web Hosting

In case you host a domain in a web hosting account from our company, all the mandatory records for using the DomainKeys Identified Mail feature will be created by default. This will happen the moment you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that your domain also uses our NS resource records. A private key will be created on our email servers, while a public key will be sent to the global DNS database automatically by using the TXT record. In this way, you won’t need to do anything manually and you’ll be able to enjoy all the benefits of this authentication system – your email messages will be delivered to any audience without being discarded and nobody will be able to send out emails faking your addresses. The latter is quite important in case the type of your Internet presence involves sending periodic offers or newsletters via email to prospective and existing customers.
