DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an email message has been sent by an authorized individual or mail server. An electronic signature is added to the message’s header using a private cryptographic key. When the email message is received, a public key that is available in the global DNS database is used to validate who exactly sent it and if its content has been modified in any way. The prime function of DomainKeys Identified Mail is to impede the widely spread spam and scam messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not get the message at all, or you’ll receive it with a warning that most probably it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email which fails the signature examination. DKIM will also give you an added layer of protection when you communicate with your business allies, for instance, as they can see for themselves that all the email messages that you send are authentic and have not been meddled with on their way.

This will happen as soon as you add the domain name in , on the condition that the domain also uses our NS resource records. A private cryptographic key will be created on our mail servers, while a public key will be sent to the global Domain Name System automatically by using the TXT resource record.
