DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email by using a digital signature. When DomainKeys Identified Mail is enabled for a certain 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 generated using the private key and when the message is received, the signature is ‘scanned’ by the receiving server using the public key. Thus, the receiver can easily discern if the email is genuine or if the sender’s email 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 delivered email messages are identical and that nothing has been added or erased. This email authentication system will increase your email safety, since you can validate the genuineness of the important emails that you get and your associates can do likewise with the email messages that you send them. Depending on the given email provider’s adopted policies, an email that fails the test may be erased or may show up in the receiver’s mailbox with a warning.

DomainKeys Identified Mail in Web Hosting

If you get one of the Linux web hosting that we’re offering, the DomainKeys Identified Mail feature will be enabled by default for any domain that you add to your shard hosting account, so you will not need to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud web hosting platform), a private key will be created instantaneously on our email servers and a TXT resource record with a public key will be sent to the DNS database. All addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are genuine, because the DKIM functionality makes it impossible for unsolicited parties to forge your addresses.
