DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email validation system, which blocks email headers from being forged and email content from being modified. This is achieved by attaching a digital signature to every email message sent from an address under a specific domain. The signature is issued on the basis of a private encryption key that’s available on the outbound SMTP mail server and it can be validated by using a public key, which is available in the global Domain Name System. Thus, any email message with changed content or a spoofed sender can be identified by mail service providers. This approach will heighten your online safety substantially and you will be sure that any message sent from a business associate, a banking institution, and so on, is a legitimate one. When you send out emails, the recipient will also know for sure that you are indeed the one who has sent them. Any mail that appears to be bogus may either be marked as such or may never show up in the recipient’s inbox, based on how the given provider has chosen to cope with such messages.

DomainKeys Identified Mail in Shared Website Hosting

In case you host a domain in a shared website hosting account from us, all the required records for using the DomainKeys Identified Mail feature will be set up by default. This will happen once you add the domain name in the Control Panel’s Hosted Domains section, on the condition that the domain also uses our NS records. A private key will be created on our mail servers, while a public key will be added to the global Domain Name System automatically by using the TXT record. In this way, you will not need to do anything manually and you’ll be able to take full advantage of all the benefits of this email authentication system – your messages will be sent to any target destination without being denied and no one will be able to send out messages faking your email addresses. The latter is quite important if the essence of your Internet presence suggests sending periodic newsletters or offers via email to prospective and existing clients.
