DomainKeys Identified Mail (DKIM) is an email validation system used to certify that an email has been sent by an authorized person or mail server. An electronic signature is added to the email’s header by using a private cryptographic key. When the message is received, a public key that is available in the global DNS database is used to verify who actually sent it and whether the content has been modified in any way. The main purpose of DomainKeys Identified Mail is to hamper the widely spread spam and scam messages, as it makes it impossible to forge an email address. If an email message is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not receive the email message at all, or you will get it with a warning notification that most probably it’s not a genuine one. It depends on email providers what exactly will happen with an email message which fails the signature test. DomainKeys Identified Mail will also supply you with an extra safety layer when you communicate with your business partners, for instance, as they can see that all the emails that you exchange are legitimate and have not been modified on their way.

DomainKeys Identified Mail in Web Hosting

If you order any of the web hosting plans that we are offering, the DomainKeys Identified Mail option will be enabled as standard for any domain that you add to your shared account, so you will not need to set up any records or to do 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 key will be generated straight away on our email servers and a TXT record with a public key will be sent to the DNS system. All email addresses created with this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will know that the messages are authentic, because the DomainKeys Identified Mail feature makes it impossible for unauthorized persons to spoof your addresses.
