DomainKeys Identified Mail, or DKIM, is a method for checking the authenticity of an email message using a digital signature. When DKIM is activated for a given domain name, a public encryption key is published to the global DNS system and a private one is stored on the mail server. If a new email message is sent, a signature is generated using the private key and when the email message is delivered, the signature is authenticated by the incoming email server using the public key. In this way, the recipient can easily distinguish if the message is authentic or if the sender’s email address has been spoofed. A discrepancy will occur if the content of the email has been changed on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This validation system will heighten your email security, as you can validate the legitimacy of the important emails that you receive and your colleagues can do the same with the emails that you send them. Based on the given email service provider’s policy, an email that fails the examination may be removed or may enter the recipient’s mailbox with a warning symbol.

This will happen the moment you add the domain name in , on the condition that it also uses our NS records. A private cryptographic key will be created on our mail servers, while a public key will be published to the DNS system automatically using the TXT resource record. In this way, you will not have to do anything manually and you will be able to enjoy all the benefits of this authentication system – your messages will be delivered to any audience without being denied and no one will be able to send email messages faking your addresses.
