DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail message has been sent by an authorized person or mail server. An electronic signature is attached to the header of the email message by using a private encryption key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and if its content has been modified in any way. The essential task of DKIM is to hinder the widespread scam and spam emails, as it makes it impossible to fake an email address. If a message is sent from an email address claiming to belong to your bank, for example, but the signature does not match, you will either not get the email at all, or you’ll get it with a warning alert that most probably it is not genuine. It depends on mail service providers what exactly will happen with an email which fails the signature examination. DomainKeys Identified Mail will also give you an added safety layer when you communicate with your business associates, for instance, since they can see that all the email messages that you send are authentic and haven’t been modified on their way.

DomainKeys Identified Mail in Shared Hosting

In case you host a domain name in a shared hosting account with us, all the obligatory records for using the DomainKeys Identified Mail option will be added by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia hosting Control Panel, provided that the domain also uses our NS records. A private encryption key will be created on our email servers, while a public key will be sent to the Domain Name System automatically by using the TXT record. In this way, you won’t have to do anything manually and you will be able to enjoy all the benefits of this email authentication system – your email messages will be delivered to any target destination without being discarded and no one will be able to send email messages faking your addresses. The latter is rather important in case the nature of your web presence suggests sending out periodic offers or newsletters via email to prospective and existing clients.
