DomainKeys Identified Mail (DKIM) is an email authentication system used to check that an e-mail message has been sent by an authenticated email server or individual. An electronic signature is added to the header of the message by using a private encryption key. When the message is received, a public key that’s available in the global DNS database is used to verify who exactly sent it and whether its content has been modified in some way. The main function of DKIM is to prevent the widespread spam and scam emails, as it makes it impossible to forge an email address. If a message 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 message at all, or you will get it with a warning alert that most probably it’s not an authentic one. It depends on email service providers what exactly will happen with an email message which fails the signature examination. DomainKeys Identified Mail will also supply you with an extra layer of protection when you communicate with your business associates, for example, since they can see for themselves that all the email messages that you exchange are genuine and have not been manipulated on their way.

DomainKeys Identified Mail in Shared Web Hosting

The DomainKeys Identified Mail option is enabled by default for all domains that are hosted in a shared web hosting account on our cloud web hosting platform, so you won’t need to do anything yourself to activate it. The only requirement is that the given domain name should be hosted in a web hosting account on our end using our MX and NS records, so that the emails will go through our email servers. The private cryptographic key will be created on the server and the TXT resource record, which contains the public key, will be published to the global Domain Name System automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DomainKeys Identified Mail email validation system will permit you to send credible emails, so if you’re sending offers or a newsletter to clients, for instance, your emails will always reach their target viewers, while unsolicited third parties will not be able to spoof your email addresses.
