DomainKeys Identified Mail (DKIM) is an email authentication system used to confirm that an email has been sent by an authenticated individual or server. An electronic signature is attached to the email’s header 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 check who actually sent it and whether the content has been edited in any way. The main job of DKIM is to hamper the widespread scam and spam messages, as it makes it impossible to fake an email address. If a message is sent from an address claiming to belong to your bank, for example, but the signature doesn’t match, you will either not receive the email at all, or you’ll receive it with a warning notice that most probably it’s not genuine. It depends on email providers what exactly will happen with an email that fails the signature examination. DKIM will also offer you an extra protection layer when you communicate with your business allies, for instance, since they can see that all the email messages that you send are genuine and have not been tampered with in the meantime.
DomainKeys Identified Mail in Cloud Hosting
If you host a domain name in a cloud hosting account from us, all the compulsory records for using the DomainKeys Identified Mail option will be set up by default. This will happen the moment you add the domain in , on the condition that your domain also uses our NS records. A private cryptographic key will be created on our email servers, whereas a public key will be published to the global Domain Name System automatically using the TXT resource record. Thus, you will not have to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your messages will reach any destination without being rejected and no one will be able to send out messages forging your email addresses. The latter is quite important if the essence of your online presence involves sending periodic newsletters or offers via email to potential and current customers.
