DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an e-mail message has been sent by an authenticated server or person. A digital signature is added to the email message’s header by using a private encryption key. When the email message is received, a public key that’s available in the global DNS database is used to confirm who exactly sent it and whether its content has been changed in some way. The primary task of DKIM is to hinder the widespread spam and scam emails, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature does not correspond, you will either not get the email message at all, or you will receive it with a warning note that most likely it’s not authentic. It depends on email service providers what exactly will happen with an email that fails the signature check. DomainKeys Identified Mail will also supply you with an extra layer of security when you communicate with your business partners, for example, as they can see for themselves that all the messages that you send are genuine and haven’t been meddled with in the meantime.

DomainKeys Identified Mail in Cloud Hosting

In case you host a domain in a cloud hosting account from our company, all the needed records for using the DomainKeys Identified Mail functionality will be set up 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 cryptographic key will be generated on our mail servers, while a public key will be published to the Domain Name System automatically using the TXT resource record. Thus, you won’t have to do anything manually and you’ll be able to make use of all the benefits of this validation system – your emails will reach any destination without being discarded and nobody will be able to send emails forging your e-mail addresses. The latter is pretty important if the essence of your web presence involves sending out periodic offers or newsletters via email to potential and current clients.
