DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email using an e-signature. When DomainKeys Identified Mail is activated for a given domain name, a public cryptographic key is published to the global DNS database and a private one is stored on the email server. When a new email message is sent, a signature is issued using the private key and when the email message is delivered, that signature is validated by the incoming POP3/IMAP server using the public key. In this way, the receiver can easily discern if the email message is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email 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 emails are identical and that nothing has been added or erased. This validation system will enhance your email security, since you can verify the authenticity of the important emails that you receive and your associates can do the exact same thing with the messages that you send them. Depending on the given email service provider’s policies, a message that fails to pass the check may be deleted or may appear in the recipient’s inbox with a warning sign.

DomainKeys Identified Mail in Hosting

When you get one of the hosting plans that we are offering, the DomainKeys Identified Mail option will be activated as standard for any domain that you register under your account, so you won’t have to set up any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS records (so that the email messages related to this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be generated immediately on our mail servers and a TXT resource record with a public key will be sent to the global DNS system. All email addresses set up with this domain name will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the recipients will know that the messages are authentic, as the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to spoof your e-mail addresses.
