DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email message by using an electronic signature. When DomainKeys Identified Mail is activated for a certain domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the mail server. If a new email is sent, a signature is generated using the private key and when the email is delivered, that signature is authenticated by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily know if the message is legitimate or if the sender’s address has been forged. A mismatch will occur if the content of the email has been changed on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the received emails are identical and that nothing has been added or erased. This email validation system will increase your email security, as you can verify the legitimacy of the important email messages that you receive and your colleagues can do the exact same thing with the emails that you send them. Based on the particular email service provider’s policy, a message that fails the check may be erased or may enter the recipient’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Website Hosting

If you obtain any of the Linux shared website hosting packages that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you register under your account, so you will not need to set up any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS resource 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 mail servers and a TXT record with a public key will be sent to the global Domain Name System. All addresses set up using 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 audience and the receivers will know that they are genuine, because the DomainKeys Identified Mail functionality makes it impossible for unauthorized persons to forge your email addresses.
