DomainKeys Identified Mail (DKIM) is an email authentication system used to certify that an e-mail message has been sent by an authorized individual or server. An electronic signature is added to the email message’s header using a private cryptographic key. When the email is received, a public key that is available in the global DNS database is used to validate who exactly sent it and whether the content has been modified in any way. The chief purpose of DomainKeys Identified Mail is to obstruct the widespread scam and spam messages, 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 or financial institution, for instance, but the signature does not match, you will either not receive the email at all, or you’ll receive it with a warning note that most probably it is not authentic. It depends on mail service providers what exactly will happen with an email message that fails to pass the signature examination. DKIM will also provide you with an additional layer of security when you communicate with your business associates, for instance, since they can see for themselves that all the emails that you exchange are legitimate and have not been modified in the meantime.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain in a shared web hosting account with us, all the required records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia Control Panel, as long as the domain also uses our NS records. A private cryptographic key will be created on our mail servers, whereas a public key will be added to the DNS database automatically by using the TXT resource record. Thus, you won’t have to do anything manually and you’ll be able to take full advantage of all the benefits of this authentication system – your emails will be sent to any destination without being discarded and nobody will be able to send email messages faking your email addresses. The latter is pretty important if the nature of your worldwide web presence suggests sending periodic newsletters or offers via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Servers

All obligatory DomainKeys Identified Mail records will be created automatically by our cloud hosting platform when you add a domain name as hosted in your semi-dedicated server account, so if you choose to order a semi-dedicated package, you will not have to configure anything to be able to take advantage of the email validation system. The domain name must use our name servers so that its DNS resource records can be managed by us and in case this condition is matched, a private cryptographic key will be generated on our email servers and a public key will be added to the DNS database by a special TXT record. All email addresses that you set up with the domain name will be protected by DKIM, which will make it impossible for 3rd parties to spoof any email address. Both you and your associates or customers can take advantage of this option, as it will guarantee a much higher protection level for your e-communication.
