DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email authentication system, which hinders email addresses from being spoofed and email content from being modified. This is done by attaching an electronic signature to every email sent from an address under a particular domain. The signature is issued on the basis of a private cryptographic key that is available on the outbound mail server and it can be verified with a public key, which is available in the global Domain Name System. In this way, any email with changed content or a forged sender can be spotted by email providers. This method will heighten your online safety substantially and you’ll know for sure that any message sent from a business ally, a bank, and so on, is authentic. When you send out messages, the receiver will also know for sure that you are indeed the one who has sent them. Any mail that appears to be forged may either be marked as such or may never end up in the recipient’s inbox, based on how the given provider has decided to treat such email messages.

DomainKeys Identified Mail in Web Hosting

In case you host a domain name in a web hosting account from us, all the obligatory records for using the DomainKeys Identified Mail feature will be set up by default. This will happen the moment you add the domain name in the Control Panel’s Hosted Domains section, as long as the domain also uses our NS records. A private encryption key will be created on our email servers, whereas a public key will be sent to the Domain Name System automatically using the TXT record. In this way, you will not have to do anything manually and you will be able to take full advantage of all the benefits of this validation system – your emails will be sent to any audience without being denied and no one will be able to send email messages faking your email addresses. The latter is rather important if the type of your web presence involves sending out periodic offers or newsletters via email to prospective and current clients.
