DomainKeys Identified Mail, or DKIM, is a method for confirming the genuineness of an email using an electronic signature. When DomainKeys Identified Mail is enabled for a certain domain, a public encryption key is published to the global DNS database and a private one is kept 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 received, that signature is verified by the incoming email server using the public key. In this way, the receiver can easily know if the message is legitimate or if the sender’s email address has been forged. A mismatch will appear if the content of the email message has been edited on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered messages are identical and that nothing has been added or removed. This validation system will boost your email security, since you can validate the legitimacy of the important email messages that you receive and your colleagues can do the same with the emails that you send them. Depending on the given email service provider’s adopted policy, an email that fails the test may be deleted or may enter the receiver’s mailbox with a warning notification.

DomainKeys Identified Mail in Cloud Hosting

In case you host a domain name in a cloud hosting account from our company, all the obligatory records for using the DomainKeys Identified Mail feature will be added by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia Control Panel, provided that the domain also uses our NS records. A private key will be created on our mail servers, while a public key will be published to the DNS system automatically using the TXT record. In this way, you will not have to do anything manually and you will be able to take advantage of all the benefits of this email validation system – your email messages will be sent to any target destination without being denied and nobody will be able to send email messages forging your email addresses. The latter is pretty important in case the essence of your web presence suggests sending periodic offers or newsletters via email to potential and current customers.
