DomainKeys Identified Mail, or DKIM, is a method for verifying the authenticity of an email by using an electronic signature. When DKIM is activated for a specific domain name, a public key is published to the global DNS 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 received, the signature is validated by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily recognize if the message is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email message has been altered in the meantime as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or erased. This validation system will increase your email security, as you can validate the authenticity of the important emails that you receive and your partners can do likewise with the email messages that you send them. Based on the particular mail service provider’s adopted policies, an email that fails the examination may be deleted or may show up in the recipient’s mailbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

When you order one of the Linux cloud packages that we are offering, the DomainKeys Identified Mail feature will be activated by default for any domain that you add to your shared account, so you will not need to create any records or to enable anything manually. When a domain is added in the Hosted Domains section of our in-house built Hepsia Control Panel using our MX and NS resource records (so that the emails associated with this domain name will be handled by our cloud web hosting platform), a private encryption key will be generated momentarily on our mail servers and a TXT record with a public key will be sent to the global DNS database. All addresses created with this domain will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will be sure that the messages are genuine, as the DKIM feature makes it impossible for unsolicited individuals to spoof your email addresses.
