DomainKeys Identified Mail, or DKIM, is a system for verifying the genuineness of an email by using an electronic signature. When DomainKeys Identified Mail is enabled 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. 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 ‘scanned’ by the incoming POP3/IMAP server using the public key. In this way, the recipient can easily distinguish if the email message is genuine or if the sender’s address has been spoofed. A mismatch will occur if the content of the email message has been changed in the meantime as well, so DKIM can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been added or erased. This email authentication system will heighten your email security, as you can verify the authenticity of the important emails that you get and your colleagues can do the same with the messages that you send them. Depending on the particular mail service provider’s policies, an email that fails to pass the test may be removed or may emerge in the receiver’s mailbox with a warning.

DomainKeys Identified Mail in Web Hosting

In case you host a domain in a web hosting account with us, all the necessary records for using the DomainKeys Identified Mail functionality will be created by default. This will happen the moment 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 key will be created on our email servers, while a public key will be added to the global DNS system automatically by using the TXT resource record. Thus, you won’t need to do anything manually and you will be able to take advantage of all the benefits of this validation system – your messages will be delivered to any destination without being discarded and no one will be able to send emails faking your e-mail addresses. The latter is quite important if the nature of your web presence suggests sending out periodic offers or newsletters via email to prospective and existing customers.
