DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email using an e-signature. When DomainKeys Identified Mail is enabled for a specific domain, a public key is published to the global Domain Name System and a private one is stored on the email server. If a new email message is sent, a signature is issued using the private key and when the email message is delivered, the signature is verified by the receiving server using the public key. Thus, the receiver can easily tell if the message is authentic or if the sender’s email address has been forged. A discrepancy will occur if the content of the email message has been edited in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or removed. This email authentication system will heighten your email safety, as you can validate the authenticity of the important email messages that you receive and your associates can do likewise with the messages that you send them. Depending on the given email service provider’s policy, a message that fails to pass the test may be removed or may end up in the recipient’s inbox with a warning.

DomainKeys Identified Mail in Hosting

In case you host a domain in a hosting account from us, all the needed records for using the DomainKeys Identified Mail option will be created by default. This will happen the moment you add the domain in , on the condition that it also uses our NS records. A private key will be generated on our mail servers, while a public key will be added to the global DNS system automatically using the TXT resource record. Thus, you won’t need to do anything manually and you’ll be able to enjoy all the benefits of this email authentication system – your messages will be sent to any target audience without being rejected and nobody will be able to send out email messages faking your e-mail addresses. The latter is pretty important if the type of your online presence suggests sending regular newsletters or offers via email to prospective and current clients.
