DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an email message has been sent by an authenticated person or server. An electronic signature is attached to the email message’s header using a private cryptographic key. When the email message is received, a public key that’s available in the global Domain Name System is used to check who actually sent it and if its content has been modified in any way. The primary job of DKIM is to avert the widely spread scam and spam email messages, 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 example, but the signature doesn’t correspond, you will either not get the message at all, or you’ll receive it with a notification that most probably it is not an authentic one. It depends on email service providers what exactly will happen with an email message which fails to pass the signature check. DomainKeys Identified Mail will also supply you with an added safety layer when you communicate with your business allies, for instance, as they can see for themselves that all the messages that you send are authentic and have not been meddled with on their way.
DomainKeys Identified Mail in Cloud Hosting
If you host a domain name in a cloud hosting account with our company, all the needed records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain in the Control Panel’s Hosted Domains section, on the condition that the domain also uses our NS resource records. A private cryptographic key will be generated on our email servers, whereas a public key will be added to the DNS database automatically using the TXT record. In this way, you will not need to do anything manually and you will be able to make use of all the benefits of this authentication system – your emails will be delivered to any audience without being rejected and no one will be able to send out messages forging your e-mail addresses. The latter is very important if the nature of your Internet presence involves sending periodic newsletters or offers via email to prospective and current customers.
