DKIM, which is an acronym for DomainKeys Identified Mail, is an authentication system, which obstructs email headers from being spoofed and email content from being tampered with. This is done by adding an e-signature to each and every message sent from an address under a specific domain. The signature is generated on the basis of a private cryptographic key that’s available on the SMTP server and it can be verified by using a public key, which is available in the global Domain Name System. In this way, any message with modified content or a forged sender can be identified by email service providers. This method will boost your web security markedly and you’ll know for sure that any email message sent from a business partner, a bank, etc., is legitimate. When you send email messages, the receiver will also be sure that you are indeed the one who has sent them. Any email that turns out to be fake may either be tagged as such or may never end up in the receiver’s mailbox, based on how the particular provider has chosen to treat such emails.

DomainKeys Identified Mail in Website Hosting

The DomainKeys Identified Mail functionality is pre-enabled for all domain names that are hosted in a website hosting account on our cloud web hosting platform, so you won’t need to do anything on your end to enable it. The only condition is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS records, so that the e-mail messages will go through our mail servers. The private encryption key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you won’t have to do anything manually on your end in order to activate this functionality. The DKIM authentication system will allow you to send out trustworthy e-mails, so if you are sending a newsletter or offers to customers, for example, your email messages will always reach their target audience, whereas unauthorized third parties will not be able to spoof your email addresses.
