DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email authentication system, which blocks email headers from being forged and email content from being tampered with. This is done by adding an electronic signature to each email message sent from an email address under a certain domain name. The signature is published based on a private cryptographic key that is available on the outbound SMTP email server and it can be validated with a public key, which is available in the global Domain Name System. In this way, any message with altered content or a forged sender can be recognized by email service providers. This method will strengthen your online safety dramatically and you’ll know for sure that any email sent from a business partner, a bank, etc., is authentic. When you send messages, the recipient will also know for sure that you are indeed the one who has sent them. Any mail that appears to be phony may either be labeled as such or may never be delivered to the receiver’s inbox, based on how the particular provider has chosen to deal with such emails.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail feature is enabled by default for all domain names that are hosted in a website hosting account on our cloud website hosting platform, so you won’t need to do anything on your end to turn it on. The only condition is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS resource records, so that the e-mails will go through our email servers. The private encryption key will be generated on the server and the TXT 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 email validation system will enable you to send out credible email messages, so if you’re sending a newsletter or offers to customers, for instance, your email messages will always reach their target audience, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
