DKIM, which is short for DomainKeys Identified Mail, is an email authentication system, which obstructs email headers from being forged and email content from being modified. This is achieved by adding an e-signature to every message sent from an email address under a given domain name. The signature is published based on a private encryption key that is available on the outbound SMTP server and it can be validated with a public key, which is available in the global DNS database. In this way, any message with altered content or a forged sender can be recognized by email service providers. This method will strengthen your web security enormously and you will know for sure that any email sent from a business collaborator, a banking institution, etc., is a legitimate one. When you send out email messages, the recipient will also know for sure that you are indeed the one who has sent them. Any email that appears to be forged may either be flagged as such or may never enter the recipient’s mailbox, depending on how the particular provider has decided to treat such messages.

DomainKeys Identified Mail in Shared Website Hosting

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