DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an e-mail message has been sent by an authenticated person or server. An electronic signature is attached to the email’s header by using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to confirm who exactly sent it and if its content has been changed in any way. The fundamental function of DomainKeys Identified Mail is to prevent the widespread spam and scam messages, as it makes it impossible to forge an email address. If a message is sent from an address claiming to belong to your bank or financial institution, for example, but the signature does not match, you will either not get the email message at all, or you will get it with a warning alert that most probably it is not a genuine one. It depends on email service providers what exactly will happen with an email that fails to pass the signature check. DomainKeys Identified Mail will also give you an added layer of safety when you communicate with your business associates, for instance, since they can see that all the e-mails that you send are genuine and have not been modified in the meantime.
DomainKeys Identified Mail in Cloud Hosting
When you get any of the cloud hosting that we offer, the DomainKeys Identified Mail option will be enabled by default for any domain name that you add to your shared web hosting account, so you will not need to create any records or to activate anything manually. When a domain name is added in the Hosted Domains section of our custom-made Hepsia Control Panel using our MX and NS records (so that the emails associated with this domain will be handled by our cloud hosting platform), a private cryptographic key will be created instantaneously on our email servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses created using this domain will be protected by DKIM, so if you send emails such as regular newsletters, they will reach their target destination and the receivers will be sure that the messages are genuine, because the DKIM feature makes it impossible for unsolicited parties to spoof your e-mail addresses.
