DKIM, which is an acronym for DomainKeys Identified Mail, is an authentication system, which prevents email headers from being forged and email content from being modified. This is achieved by attaching an electronic signature to every message sent from an email address under a specific domain name. The signature is published based on a private cryptographic key that is available on the outbound mail server and it can be verified using a public key, which is available in the global DNS database. In this way, any email with changed content or a spoofed sender can be recognized by mail service providers. This approach will strengthen your web security tremendously and you’ll know for sure that any e-mail sent from a business partner, a banking institution, and so on, is authentic. 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 turns out to be phony may either be labeled as such or may never be delivered to the recipient’s inbox, depending on how the given provider has chosen to handle such messages.

DomainKeys Identified Mail in Shared Hosting

If you host a domain in a shared hosting account from our company, all the mandatory records for using the DomainKeys Identified Mail option will be set up by default. This will happen as soon as you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that the domain also uses our NS resource records. A private key will be generated on our email servers, whereas a public key will be published to the Domain Name System automatically by using the TXT record. In this way, you won’t need to do anything manually and you will be able to enjoy all the benefits of this validation system – your email messages will be delivered to any target audience without being denied and no one will be able to send emails forging your email addresses. The latter is very important if the type of your online presence suggests sending out periodic offers or newsletters via email to potential and current clients.
