DKIM, which is an abbreviation for DomainKeys Identified Mail, is an authentication system, which blocks email headers from being spoofed and email content from being tampered with. This is achieved by attaching an e-signature to each email sent from an email address under a certain domain. The signature is issued based on a private key that’s available on the outbound SMTP mail server and it can be verified with a public key, which is available in the global DNS database. Thus, any email message with altered content or a spoofed sender can be identified by email providers. This method will heighten your worldwide web security greatly and you will know for sure that any message sent from a business partner, a bank, and so on, is genuine. When you send email messages, the recipient will also be sure that you are indeed the one who has sent them. Any email message that appears to be phony may either be labeled as such or may never enter the receiver’s mailbox, depending on how the given provider has decided to deal with such emails.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail functionality is pre-activated for all domains that are hosted in a web hosting account on our cloud web hosting platform, so you won’t need to do anything yourself to turn it on. The sole condition is that the particular domain should be hosted in a web hosting account on our platform using our MX and NS records, so that the email messages will go through our email servers. The private cryptographic 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 won’t have to do anything manually on your end in order to enable this feature. The DomainKeys Identified Mail email authentication system will enable you to send out credible emails, so if you’re sending offers or a newsletter to customers, for instance, your emails will always reach their target viewers, whereas unsolicited 3rd parties won’t be able to spoof your email addresses.
