DomainKeys Identified Mail, or DKIM, is a system for verifying the authenticity of an email message using a digital signature. When DomainKeys Identified Mail is enabled for a specific domain name, a public encryption key is published to the global DNS database and a private one is kept on the mail server. If a new email is sent, a signature is issued using the private key and when the email message is received, that signature is validated by the incoming server using the public key. Thus, the recipient can easily discern if the message is legitimate or if the sender’s email address has been forged. A discrepancy will appear if the content of the email has been modified on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered messages are identical and that nothing has been added or deleted. This authentication system will strengthen your email security, since you can confirm the genuineness of the important email messages that you receive and your associates can do the same with the email messages that you send them. Depending on the particular email provider’s policy, an email that fails the examination may be removed or may show up in the recipient’s inbox with a warning flag.

DomainKeys Identified Mail in Cloud Web Hosting

If you buy any of the cloud web hosting plans that we offer, the DomainKeys Identified Mail feature will be activated as standard for any domain name that you add to your website hosting 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 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 key will be issued momentarily on our mail servers and a TXT record with a public key will be sent to the global DNS database. All email addresses created using this domain name will be protected by DKIM, so if you send out email messages such as regular newsletters, they will reach their target destination and the recipients will know that they are legitimate, since the DomainKeys Identified Mail functionality makes it impossible for unauthorized individuals to forge your addresses.
