DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email using a digital signature. When DomainKeys Identified Mail is activated for a given domain name, a public encryption key is published to the global DNS database and a private one is kept on the email server. If a new email is sent, a signature is generated using the private key and when the message is delivered, the signature is authenticated by the incoming server using the public key. Thus, the recipient can easily discern if the message is authentic or if the sender’s email address has been forged. A discrepancy will occur if the content of the email has been edited in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been added or erased. This authentication system will strengthen your email security, since you can validate the authenticity of the important email messages that you receive and your partners can do likewise with the messages that you send them. Depending on the given email provider’s adopted policy, a message that fails to pass the examination may be removed or may end up in the recipient’s mailbox with a warning alert.

DomainKeys Identified Mail in Web Hosting

If you purchase one of the Linux web hosting packages that we’re offering, the DomainKeys Identified Mail feature will be enabled as standard for any domain name that you register under your shard hosting account, so you will not have to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain will be handled by our cloud web hosting platform), a private cryptographic key will be generated immediately on our email servers and a TXT record with a public key will be sent to the DNS system. All addresses created using this domain will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the receivers will know that the messages are legitimate, as the DomainKeys Identified Mail functionality makes it impossible for unauthorized people to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All compulsory DomainKeys Identified Mail records will be set up automatically by our cloud hosting platform when you add a domain as hosted in a semi-dedicated server account, so if you choose to order a semi-dedicated server plan, you won’t need to set up anything to be able to use the email validation system. The domain should use our name servers so that its DNS records can be managed by our company and if this prerequisite is met, a private key will be generated on our email servers and a public key will be published to the global DNS system by a special TXT resource record. All addresses that you create with the domain name will be protected by DKIM, which will make it impossible for third parties to fake any email address. Both you and your associates or customers can benefit from this feature, as it will ensure a much higher level of security for your email communication.
