DomainKeys Identified Mail (DKIM) is an email authentication system used to verify that an email has been sent by an authorized mail server or individual. A digital signature is attached to the header of the message by using a private cryptographic key. When the message is received, a public key that’s available in the global DNS database is used to confirm who actually sent it and if the content has been changed in any way. The principal task of DomainKeys Identified Mail is to stop the widespread spam and scam email messages, as it makes it impossible to fake 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 doesn’t correspond, you will either not get the message at all, or you will receive it with a warning notice that most likely it is not genuine. It depends on email service providers what exactly will happen with an email message which fails to pass the signature examination. DKIM will also supply you with an additional security layer when you communicate with your business associates, for instance, as they can see for themselves that all the email messages that you exchange are genuine and haven’t been tampered with on their way.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail feature is pre-activated for all domains that are hosted in a cloud hosting account on our cloud platform, so you will not have to do anything on your end to turn it on. The only condition is that the particular domain should be hosted in a web 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 encryption key will be created on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you will not need to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail validation system will enable you to send out trustable e-mails, so if you’re sending a newsletter or offers to clients, for instance, your emails will always reach their target audience, while unauthorized 3rd parties will not be able to spoof your email addresses.
