DomainKeys Identified Mail (DKIM) is a validation system used to certify that an e-mail has been sent by an authenticated server or person. An electronic signature is attached to the header of the email by using a private cryptographic key. When the message is received, a public key that is available in the global Domain Name System is used to verify who actually sent it and if its content has been changed in any way. The fundamental task of DomainKeys Identified Mail is to hamper the widely spread scam and spam emails, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank, for instance, but the signature doesn’t match, you will either not receive the email message at all, or you’ll get it with a warning that most likely it is not an authentic one. It depends on email service providers what exactly will happen with an email that fails to pass the signature test. DKIM will also offer you an additional layer of protection when you communicate with your business partners, for example, since they can see for themselves that all the emails that you send are legitimate and haven’t been manipulated on their way.

DomainKeys Identified Mail in Cloud Hosting

When you order any of the Linux cloud packages that we’re offering, the DomainKeys Identified Mail feature will be activated as standard for any domain that you register under your website hosting account, so you won’t have to set up 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 MX and NS resource records (so that the email messages associated with this domain will be handled by our cloud hosting platform), a private encryption key will be generated instantaneously on our email servers and a TXT resource 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 email messages such as regular newsletters, they will reach their target audience and the recipients will be sure that the messages are authentic, because the DKIM option makes it impossible for unauthorized people to forge your email addresses.
