DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email message by using a digital signature. When DKIM is activated for a particular domain, a public cryptographic key is published to the global DNS system and a private one is kept on the email server. When a new message is sent, a signature is generated using the private key and when the email is received, the signature is ‘scanned’ by the receiving server using the public key. In this way, the recipient can easily discern if the message is legitimate or if the sender’s email address has been forged. A mismatch will occur if the content of the email has been changed on its way as well, so DKIM can also be used to ensure that the sent and the delivered messages are identical and that nothing has been attached or erased. This email validation system will enhance your email safety, as you can confirm the authenticity of the important emails that you receive and your colleagues can do the exact same thing with the emails that you send them. Based on the particular mail service provider’s policies, an email that fails to pass the examination may be erased or may emerge in the receiver’s mailbox with a warning notification.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain name in a shared hosting account from us, all the obligatory records for using the DomainKeys Identified Mail feature will be created by default. This will happen as soon as you add the domain name in , on the condition that your domain also uses our NS records. A private key will be created on our email servers, while a public key will be added to the DNS system automatically by using the TXT record. In this way, you will not have to do anything manually and you’ll be able to take advantage of all the benefits of this authentication system – your messages will be delivered to any destination without being rejected and nobody will be able to send out messages forging your email addresses. The latter is quite important in case the nature of your worldwide web presence suggests sending regular offers or newsletters via email to prospective and existing customers.
