DomainKeys Identified Mail (DKIM) is a validation system used to prove that an e-mail has been sent by an authorized person or server. An electronic signature is added to the header of the email using a private key. When the email is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and whether its content has been changed in any way. The primary task of DKIM is to avert the widespread spam and scam messages, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for instance, but the signature does not correspond, you will either not receive the message at all, or you will get it with a warning alert that most probably it is not an authentic one. It depends on email providers what exactly will happen with an email that fails to pass the signature check. DomainKeys Identified Mail will also give you an extra safety layer when you communicate with your business allies, for example, since they can see that all the messages that you exchange are genuine and have not been tampered with on their way.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail option is pre-activated for all domains that are hosted in a web hosting account on our cloud hosting platform, so you will not have to do anything yourself to enable it. The sole condition is that the particular domain should be hosted in an account on our platform using our MX and NS records, so that the e-mail messages will go through our mail servers. The private key will be generated on the server and the TXT resource record, which contains the public key, will be published to the global DNS system automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DKIM authentication system will enable you to send credible e-mail messages, so if you are sending offers or a newsletter to clients, for example, your emails will always reach their target destination, while unauthorized 3rd parties won’t be able to forge your email addresses.
