DomainKeys Identified Mail (DKIM) is a validation system used to certify that an email has been sent by an authorized individual or mail server. A digital signature is attached to the header of the email message by using a private 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 whether the content has been altered in some way. The prime purpose of DomainKeys Identified Mail is to hamper the widely spread 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 instance, but the signature doesn’t correspond, you will either not get the email message at all, or you’ll receive it with a notification that most likely it’s not authentic. It depends on email providers what exactly will happen with an email message which fails the signature check. DKIM will also supply you with an additional safety layer when you communicate with your business associates, for instance, as they can see that all the email messages that you send are legitimate and have not been modified on their way.
DomainKeys Identified Mail in Shared Website Hosting
The DomainKeys Identified Mail option is enabled by default for all domains that are hosted in a shared website hosting account on our cloud web hosting platform, so you will not need to do anything yourself to enable it. The only requirement is that the particular domain should be hosted in a hosting account on our platform using our NS and MX records, so that the e-mail messages will go through our email servers. The private encryption key will be created on the server and the TXT resource record, which contains the public key, will be published to the DNS database automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DKIM email validation system will permit you to send trustable emails, so if you’re sending a newsletter or offers to clients, for example, your emails will always reach their target viewers, whereas unsolicited 3rd parties will not be able to forge your email addresses.
