DomainKeys Identified Mail, or DKIM, is a method for validating the legitimacy of an email using an e-signature. When DomainKeys Identified Mail is enabled for a particular domain, a public encryption key is published to the global Domain Name System and a private one is kept on the email server. When a new email is sent, a signature is generated using the private key and when the email message is received, that signature is ‘scanned’ by the POP3/IMAP email server using the public key. In this way, the recipient can easily know if the email message is authentic or if the sender’s email address has been forged. A discrepancy will occur if the content of the email has been modified on its way as well, so DKIM can also be used to make sure that the sent and the delivered messages are identical and that nothing has been attached or deleted. This email validation system will heighten your email security, since you can validate the authenticity of the important email messages that you receive and your partners can do likewise with the messages that you send them. Based on the particular email service provider’s policies, an email message that fails the examination may be deleted or may reach the receiver’s inbox with a warning flag.

DomainKeys Identified Mail in Web Hosting

If you host a domain in a web hosting account with our company, all the mandatory records for using the DomainKeys Identified Mail option will be added by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, on the condition that your domain also uses our NS records. A private encryption key will be created on our mail servers, whereas a public key will be added to the global Domain Name System automatically using the TXT record. In this way, you won’t need to do anything manually and you’ll be able to take full advantage of all the benefits of this validation system – your messages will reach any target audience without being disallowed and nobody will be able to send out messages forging your email addresses. The latter is pretty important in case the nature of your online presence suggests sending out regular newsletters or offers via email to potential and existing clients.
