DomainKeys Identified Mail (DKIM) is a validation system used to confirm that an email has been sent by an authenticated mail server or person. An electronic signature is added to the email’s header using a private key. When the email message is received, a public key that’s available in the global DNS database is used to validate who actually sent it and whether its content has been altered in some way. The primary job of DomainKeys Identified Mail is to avert the widespread spam and scam messages, as it makes it impossible to fake an email address. If an email message is sent from an email address claiming to belong to your bank, for example, but the signature doesn’t correspond, you will either not get the message at all, or you’ll get it with a notification that most likely it is not authentic. It depends on email service providers what exactly will happen with an email message that fails the signature check. DKIM will also give you an extra protection layer when you communicate with your business associates, for example, as they can see for themselves that all the emails that you send are legitimate and have not been meddled with on their way.

DomainKeys Identified Mail in Cloud Hosting

If you buy one of the Linux cloud hosting that we’re offering, the DomainKeys Identified Mail feature will be activated as standard for any domain that you register under your website hosting account, so you will not need to set up any records or to enable anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX records (so that the email messages associated with this domain will be handled by our cloud hosting platform), a private cryptographic key will be issued straight away on our mail servers and a TXT record with a public key will be sent to the DNS database. All addresses created using 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, because the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to spoof your email addresses.
