DomainKeys Identified Mail (DKIM) is an authentication system used to verify that an e-mail message has been sent by an authorized server or individual. A digital signature is added to the message’s header 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 if its content has been changed in any way. The essential job of DomainKeys Identified Mail is to stop the widespread spam and scam email messages, as it makes it impossible to forge an email address. If an email is sent from an email address claiming to belong to your bank, for instance, but the signature does not match, you will either not get the email at all, or you’ll receive it with a notification that most probably it is not a genuine one. It depends on mail service providers what exactly will happen with an email message which fails to pass the signature check. DKIM will also supply you with an added protection layer when you communicate with your business partners, for example, since they can see for themselves that all the e-mails that you exchange are genuine and haven’t been manipulated in the meantime.

DomainKeys Identified Mail in Cloud Website Hosting

The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a cloud website hosting account on our cloud hosting platform, so you will not need to do anything yourself to enable it. The only requirement is that the particular domain name should be hosted in a hosting account on our end using our MX and NS resource records, so that the emails will go through our mail 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 DNS system automatically, so you will not have to do anything manually on your end in order to activate this option. The DomainKeys Identified Mail email validation system will allow you to send out credible emails, so if you are sending a newsletter or offers to customers, for example, your email messages will always reach their target audience, while unauthorized third parties won’t be able to spoof your email addresses.
