DomainKeys Identified Mail, or DKIM, is a system for checking the legitimacy of an email by using an e-signature. When DomainKeys Identified Mail is enabled for a given domain name, a public key is published to the global DNS system and a private one is kept on the mail server. When a new email is sent, a signature is issued using the private key and when the message is delivered, that signature is ‘scanned’ by the POP3/IMAP server using the public key. In this way, the receiver can easily know if the email message is legitimate or if the sender’s address has been spoofed. A discrepancy will occur if the content of the email message has been edited on its way 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 erased. This email validation system will enhance your email security, since you can validate the authenticity of the important email messages that you receive and your associates can do the exact same thing with the messages that you send them. Depending on the given mail service provider’s policy, an email that fails to pass the test may be erased or may end up in the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Shared Hosting

When you purchase any of the shared packages that we are offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain that you add to your website 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-developed Hepsia Control Panel using our NS and MX records (so that the emails associated with this domain will be handled by our cloud hosting platform), a private key will be created immediately on our email servers and a TXT resource record with a public key will be sent to the global DNS database. All addresses set up using this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will be sure that they are authentic, since the DomainKeys Identified Mail functionality makes it impossible for unauthorized persons to forge your email addresses.
