DomainKeys Identified Mail, or DKIM, is a system for checking the genuineness of an email message using a digital signature. When DomainKeys Identified Mail is activated for a given domain, a public encryption key is published to the global Domain Name System and a private one is stored 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 delivered, that signature is validated by the incoming mail server using the public key. Thus, the receiver can easily distinguish if the message is genuine or if the sender’s email address has been forged. A discrepancy will occur if the content of the email has been modified in the meantime 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 removed. This validation system will boost your email security, since you can validate the genuineness of the important emails that you receive and your colleagues can do the same with the messages that you send them. Based on the given email service provider’s policy, an email message that fails the examination may be removed or may end up in the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Website Hosting

If you host a domain in a website hosting account from us, all the obligatory records for using the DomainKeys Identified Mail option will be set up by default. This will happen once you add the domain name in the Hosted Domains section of the Hepsia hosting Control Panel, provided that it also uses our NS resource records. A private key will be generated on our email servers, while a public key will be published to the DNS database automatically using the TXT resource record. Thus, you will not have to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your emails will be delivered to any audience without being disallowed and no one will be able to send out messages faking your email addresses. The latter is very important if the essence of your Internet presence involves sending regular newsletters or offers via email to potential and current clients.
