DomainKeys Identified Mail (DKIM) is an email validation system used to check that an email has been sent by an authenticated mail server or person. An e-signature is attached to the email message’s header using a private cryptographic key. When the email is received, a public key that’s available in the global Domain Name System is used to verify who actually sent it and if the content has been changed in some way. The prime purpose of DomainKeys Identified Mail is to stop the widespread scam and spam emails, as it makes it impossible to forge an email address. If an email is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not receive the email at all, or you will get it with a warning notice that most likely it’s not genuine. It depends on email service providers what exactly will happen with an email message that fails to pass the signature test. DomainKeys Identified Mail will also supply you with an extra safety layer when you communicate with your business associates, for instance, as they can see that all the email messages that you exchange are authentic and haven’t been modified on their way.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail functionality is activated by default for all domains that are hosted in a hosting account on our cloud servers, so you will not need to do anything on your end to turn it on. The sole requirement is that the particular domain name should be hosted in a website hosting account on our end using our MX and NS records, so that the emails will go through our mail servers. The private cryptographic key will be generated 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 enable this feature. The DKIM email validation system will permit you to send credible email messages, so if you are sending offers or a newsletter to clients, for instance, your emails will always reach their target destination, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.
