DomainKeys Identified Mail (DKIM) is a validation system used to prove that an email has been sent by an authorized individual or server. A digital signature is attached to the header of the email message using a private key. When the message is received, a public key that’s available in the global Domain Name System is used to verify who exactly sent it and whether the content has been modified in any way. The essential function of DomainKeys Identified Mail is to impede the widespread spam and scam emails, as it makes it impossible to fake an email address. If an email is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t match, you will either not receive the email at all, or you’ll receive it with a notification that most likely it’s not legitimate. It depends on email providers what exactly will happen with an email which fails to pass the signature test. DomainKeys Identified Mail will also give you an extra protection layer when you communicate with your business partners, for example, since they can see that all the e-mails that you exchange are authentic and haven’t been meddled with in the meantime.

DomainKeys Identified Mail in Shared Website Hosting

If you purchase any of the Linux shared website hosting that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you register under your account, so you will not have to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our MX and NS resource records (so that the emails associated with this domain will be handled by our cloud hosting platform), a private encryption key will be issued right away on our mail servers and a TXT resource record with a public key will be sent to the global Domain Name System. All email addresses set up with this domain will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target audience and the receivers will know that they are authentic, since the DomainKeys Identified Mail feature makes it impossible for unauthorized parties to forge your email addresses.
