DomainKeys Identified Mail (DKIM) is an email validation system used to prove that an e-mail message has been sent by an authenticated mail server or person. An e-signature is attached to the header of the email message using a private encryption key. When the email message is received, a public key that’s available in the global Domain Name System is used to confirm who actually sent it and whether its content has been altered in some way. The primary function of DKIM is to block the widely spread spam and scam messages, 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 at all, or you’ll receive it with a warning note that most probably it’s not a legitimate one. It depends on mail service providers what exactly will happen with an email message that fails the signature examination. DKIM will also give you an additional security layer when you communicate with your business associates, for instance, since they can see that all the e-mails that you exchange are authentic and have not been manipulated on their way.

DomainKeys Identified Mail in Shared Website Hosting

The DomainKeys Identified Mail option is pre-activated for all domains that are hosted in a shared website hosting account on our cloud platform, so you won’t have to do anything yourself to turn it on. The only condition is that the given domain name should be hosted in a website hosting account on our platform using our MX and NS resource records, so that the email messages will go through our email servers. The private key will be generated on the server and the TXT resource record, which contains the public key, will be published to the DNS database automatically, so you will not need to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail authentication system will enable you to send out trustworthy messages, so if you’re sending offers or a newsletter to clients, for instance, your emails will always reach their target viewers, while unauthorized 3rd parties won’t be able to spoof your email addresses.
