DomainKeys Identified Mail, or DKIM, is a system for validating the genuineness of an email using an e-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. When a new email is sent, a signature is generated using the private key and when the email is received, that signature is authenticated by the incoming mail server using the public key. Thus, the receiver can easily tell if the email 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 changed in the meantime as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or erased. This email validation system will boost your email safety, since you can confirm the legitimacy of the important emails that you receive and your colleagues can do the exact same thing with the emails that you send them. Based on the given email service provider’s adopted policy, an email that fails the test may be erased or may enter the receiver’s mailbox with a warning notification.

DomainKeys Identified Mail in Shared Web Hosting

If you order any of the shared web hosting that we’re offering, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you register under your hosting account, so you won’t have to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS resource records (so that the email messages associated with this domain will be handled by our cloud hosting platform), a private encryption key will be created right away on our mail servers and a TXT record with a public key will be sent to the global DNS database. All email addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send out emails such as regular newsletters, they will reach their target destination and the recipients will be sure that the messages are legitimate, as the DKIM feature makes it impossible for unsolicited parties to forge your e-mail addresses.
