DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail message has been sent by an authenticated person or server. An e-signature is attached to the header of the email by using a private key. When the email is received, a public key that’s available in the global DNS database is used to validate who exactly sent it and if its content has been edited in some way. The fundamental purpose of DKIM is to hinder the widely spread scam and spam messages, 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 or financial institution, for example, but the signature doesn’t correspond, you will either not receive the message at all, or you’ll receive it with a warning alert that most likely it is not a genuine one. It depends on mail service providers what exactly will happen with an email that fails the signature examination. DKIM will also offer you an additional layer of security when you communicate with your business allies, for example, since they can see that all the emails that you exchange are authentic and have not been manipulated on their way.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail option is pre-activated for all domain names that are hosted in a web hosting account on our cloud website hosting platform, so you will not have to do anything yourself to activate it. The sole condition is that the particular domain should be hosted in a website hosting account on our platform using our NS and MX resource records, so that the e-mail messages will go through our email servers. The private cryptographic key will be created on the server and the TXT record, which includes the public key, will be published to the global Domain Name System automatically, so you won’t need to do anything manually on your end in order to enable this feature. The DKIM email authentication system will allow you to send out trustworthy email 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 forge your email addresses.
