DomainKeys Identified Mail (DKIM) is an email authentication system used to prove that an e-mail has been sent by an authenticated mail server or person. A digital signature is added to the header of the email message by using a private key. When the message is received, a public key that is available in the global Domain Name System is used to validate who exactly sent it and whether its content has been modified in some way. The primary job of DomainKeys Identified Mail is to impede the widely spread spam and scam email messages, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not receive the message at all, or you’ll receive it with a warning note that most probably it’s not authentic. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature check. DomainKeys Identified Mail will also offer you an extra layer of security when you communicate with your business allies, for example, as they can see that all the e-mail messages that you exchange are genuine and haven’t been tampered with on their way.

DomainKeys Identified Mail in Web Hosting

If you get one of the web hosting plans that we are offering, the DomainKeys Identified Mail feature will be activated as standard for any domain name that you register under your web hosting account, so you won’t need to create any records or to do anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our NS and MX resource records (so that the email messages associated with this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be issued momentarily on our email servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses created using this domain name will be protected by DomainKeys Identified Mail, so if you send out email messages such as periodic newsletters, they will reach their target destination and the recipients will know that the messages are authentic, because the DomainKeys Identified Mail feature makes it impossible for unauthorized people to forge your addresses.
