DomainKeys Identified Mail, or DKIM, is a method for confirming the legitimacy of an email by using an electronic signature. When DKIM is activated for a particular domain name, a public encryption key is published to the global DNS system and a private one is kept on the email server. When a new email message is sent, a signature is issued using the private key and when the email is delivered, the signature is validated by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily discern if the message is authentic or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email message has been modified on its way as well, so DKIM can also be used to ensure that the sent and the received messages are identical and that nothing has been attached or deleted. This email authentication system will enhance your email safety, since you can validate the authenticity of the important email messages that you get and your colleagues can do the same with the emails that you send them. Depending on the given mail service provider’s policies, an email message that fails to pass the test may be deleted or may appear in the receiver’s inbox with a warning sign.

DomainKeys Identified Mail in Cloud Website Hosting

In case you host a domain in a cloud website hosting account from us, all the compulsory records for using the DomainKeys Identified Mail option will be set up by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, as long as the domain also uses our NS records. A private key will be created on our email servers, whereas a public key will be sent to the DNS system automatically using the TXT resource record. In this way, you will not need to do anything manually and you will be able to take advantage of all the benefits of this authentication system – your messages will reach any target destination without being disallowed and no one will be able to send out email messages faking your e-mail addresses. The latter is really important if the type of your worldwide web presence suggests sending regular newsletters or offers via email to prospective and existing customers.
