DomainKeys Identified Mail (DKIM) is an authentication system used to certify that an e-mail has been sent by an authorized person or mail server. An electronic signature is added to the header of the 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 actually sent it and whether the content has been altered in any way. The fundamental job of DomainKeys Identified Mail is to hinder the widespread spam and scam emails, as it makes it impossible to fake an email address. If an email message is sent from an address claiming to belong to your bank, for example, but the signature does not match, you will either not receive the email at all, or you’ll receive it with an alert that most probably it’s not a genuine one. It depends on email providers what exactly will happen with an email message that fails to pass the signature check. DKIM will also supply you with an added protection layer when you communicate with your business associates, for instance, since they can see that all the email messages that you exchange are genuine and haven’t been modified on their way.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail feature is pre-enabled for all domains that are hosted in a hosting account on our cloud platform, so you won’t have to do anything on your end to enable it. The sole requirement is that the particular domain should be hosted in a web hosting account on our platform using our NS and MX records, so that the emails will go through our mail servers. The private encryption key will be created on the server and the TXT resource record, which includes the public key, will be published to the DNS database automatically, so you won’t need to do anything manually on your end in order to activate this option. The DKIM email validation system will permit you to send credible e-mail messages, so if you’re sending a newsletter or offers to clients, for instance, your email messages will always reach their target destination, whereas unsolicited third parties won’t be able to spoof your email addresses.
