DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email has been sent by an authorized person or server. An e-signature is attached to the header of the message by using a private key. When the email is received, a public key that is available in the global Domain Name System is used to verify who exactly sent it and if the content has been modified in some way. The fundamental task of DKIM is to block the widespread spam and scam emails, as it makes it impossible to forge an email address. If a message 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 will get it with a warning notice that most likely it’s not an authentic one. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature check. DomainKeys Identified Mail will also supply you with an added layer of safety when you communicate with your business partners, for example, as they can see that all the emails that you exchange are authentic and haven’t been tampered with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

If you host a domain name in a cloud hosting account with us, all the obligatory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen once you add the domain in the Control Panel’s Hosted Domains section, provided that your domain also uses our NS records. A private key will be created on our mail servers, while a public key will be published to the global Domain Name System automatically using the TXT record. In this way, you will not need to do anything manually and you will be able to take advantage of all the benefits of this authentication system – your messages will be sent to any target audience without being discarded and nobody will be able to send out messages forging your email addresses. The latter is rather important in case the essence of your online presence involves sending regular offers or newsletters via email to prospective and existing customers.
