DomainKeys Identified Mail, or DKIM, is a method for verifying the genuineness of an email using an e-signature. When DomainKeys Identified Mail is enabled for a specific domain name, 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 message is sent, a signature is generated using the private key and when the email message is delivered, the signature is verified by the incoming POP3/IMAP mail server using the public key. In this way, the recipient can easily know if the email message is legitimate or if the sender’s email address has been spoofed. A mismatch will appear if the content of the email message has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the received emails are identical and that nothing has been attached or deleted. This email validation system will enhance your email security, since you can verify the authenticity of the important emails that you get and your colleagues can do likewise with the emails that you send them. Based on the given email provider’s adopted policy, a message that fails to pass the examination may be erased or may emerge in the recipient’s inbox with a warning.

DomainKeys Identified Mail in Cloud Hosting

When you purchase any of the Linux cloud packages that we offer, the DomainKeys Identified Mail functionality will be activated by default for any domain that you add to your account, so you will not need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX records (so that the emails associated with this domain will be handled by our cloud web hosting platform), a private encryption key will be generated instantaneously on our email servers and a TXT record with a public key will be sent to the DNS system. All addresses set up with this domain will be protected by DKIM, so if you send out emails such as regular newsletters, they will reach their target destination and the receivers will know that the messages are authentic, as the DKIM feature makes it impossible for unsolicited people to spoof your email addresses.
