DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an e-mail has been sent by an authorized mail server or individual. An e-signature is added to the header of the email using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to check who exactly sent it and whether its content has been edited in some way. The fundamental purpose of DKIM is to prevent the widely spread spam and scam email messages, as it makes it impossible to fake an email address. If an email is sent from an address claiming to belong to your bank, for instance, but the signature does not match, you will either not get the email at all, or you’ll get it with a warning notice that most probably it’s not a genuine one. It depends on email service providers what exactly will happen with an email message which fails the signature examination. DKIM will also offer you an extra protection layer when you communicate with your business associates, for instance, since they can see that all the e-mails that you exchange are genuine and have not been modified on their way.

DomainKeys Identified Mail in Hosting

If you host a domain name in a hosting account from our company, all the required records for using the DomainKeys Identified Mail feature will be added by default. This will happen once you add the domain name in , on the condition that it also uses our NS resource records. A private cryptographic key will be created on our email servers, while a public key will be sent to the global Domain Name System automatically using the TXT record. Thus, you won’t have to do anything manually and you’ll be able to make use of all the benefits of this authentication system – your messages will reach any target destination without being denied and nobody will be able to send out messages forging your addresses. The latter is quite important if the type of your online presence involves sending periodic newsletters or offers via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Servers

All required DKIM records will be set up automatically by our cloud web hosting platform when you add a domain as hosted in your semi-dedicated server account, so in case you decide to use this type of hosting, you won’t have to set up anything to be able to take advantage of the email authentication system. The domain must use our name servers in order for its DNS resource records to be managed by our company and in case this prerequisite is matched, a private key will be created on our mail servers and a public key will be published to the DNS system by a special TXT record. All email addresses that you set up using the domain will be protected by DKIM, which will make it impossible for 3rd parties to spoof any address. Both you and your associates or clients can take advantage of this option, as it will guarantee a higher protection level for your email correspondence.
