DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an e-mail message has been sent by an authorized server or person. An electronic signature is attached to the email message’s header by using a private encryption key. When the email is received, a public key that is available in the global Domain Name System is used to check who exactly sent it and if the content has been altered in any way. The fundamental job of DKIM is to prevent the widely spread scam and spam email messages, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank or financial institution, for instance, but the signature doesn’t correspond, you will either not receive the message at all, or you will receive it with a warning note that most probably it is not authentic. It depends on email providers what exactly will happen with an email message that fails to pass the signature test. DomainKeys Identified Mail will also supply you with an additional security layer when you communicate with your business associates, for instance, as they can see for themselves that all the emails that you send are authentic and haven’t been modified on their way.

DomainKeys Identified Mail in Hosting

If you host a domain in a hosting account from us, all the needed records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain name in , as long as your domain also uses our NS resource records. A private key will be created on our email servers, whereas a public key will be sent to the global Domain Name System automatically using the TXT record. Thus, you won’t need to do anything manually and you’ll be able to take advantage of all the benefits of this email authentication system – your emails will reach any destination without being disallowed and no one will be able to send emails faking your addresses. The latter is quite important if the nature of your Internet presence suggests sending regular newsletters or offers via email to potential and existing customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our semi-dedicated packages come with DKIM enabled by default, so if you choose this type of hosting and you add a domain name using our name servers via your Hepsia Control Panel, the records required for the email authentication system will be set up automatically – a private cryptographic key on our mail servers for the digital signature and a TXT resource record carrying the public key for the global Domain Name System. As the DKIM protection is set up for a given domain, all e-mail addresses created with it will carry a signature, so you will not have to worry that the emails that you send may not reach their destination email address or that someone may spoof any of your addresses and try to scam/spam people. This may be really important when you rely on email communication in your business, as your associates and/or clients will be able to distinguish legitimate emails from false ones.
