DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an e-mail has been sent by an authorized person or mail server. A digital signature is added to the header of the email message by using a private key. When the email message is received, a public key that is available in the global Domain Name System is used to confirm who exactly sent it and whether the content has been modified in some way. The fundamental job of DKIM is to prevent the widespread spam and scam emails, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank or financial institution, for example, but the signature doesn’t correspond, you will either not receive the email at all, or you’ll receive it with a warning notice that most likely it’s not genuine. It depends on email providers what exactly will happen with an email which fails to pass the signature test. DomainKeys Identified Mail will also give you an additional protection layer when you communicate with your business associates, for instance, as they can see for themselves that all the e-mails that you exchange are authentic and haven’t been modified on their way.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail feature is enabled by default for all domain names that are hosted in a cloud website hosting account on our cloud servers, so you will not have to do anything yourself to activate it. The only condition is that the given domain name should be hosted in an account on our end using our NS and MX resource records, so that the e-mails will go through our mail servers. The private encryption key will be created on the server and the TXT record, which contains the public key, will be published to the global Domain Name System automatically, so you will not have to do anything manually on your end in order to enable this feature. The DKIM authentication system will allow you to send out trustworthy e-mail messages, so if you’re sending offers or a newsletter to customers, for example, your emails will always reach their target audience, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
