DomainKeys Identified Mail (DKIM) is an authentication system used to prove that an e-mail has been sent by an authenticated person or mail server. An electronic signature is attached to the message’s header using a private cryptographic key. When the message is received, a public key that is available in the global Domain Name System is used to verify who actually sent it and if its content has been modified in any way. The primary task of DKIM is to hinder the widespread scam and spam email 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 example, but the signature does not correspond, you will either not receive the email at all, or you will get it with a warning notification that most likely it’s not an authentic one. It depends on email service providers what exactly will happen with an email message that fails the signature examination. DKIM will also supply you with an extra layer of protection when you communicate with your business allies, for instance, as they can see for themselves that all the e-mail messages that you send are authentic and haven’t been modified on their way.

DomainKeys Identified Mail in Shared Website Hosting

When you purchase any of the shared website hosting that we’re offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain that you add to your web hosting account, so you will not have to create any records or to activate anything manually. When a domain is added in the Hosted Domains section of our custom Hepsia Control Panel using our NS and MX resource records (so that the email messages related to this domain will be handled by our cloud platform), a private cryptographic key will be created straight away on our email servers and a TXT resource record with a public key will be sent to the DNS database. All email addresses set up using this domain will be protected by DKIM, so if you send out email messages such as periodic newsletters, they will reach their target audience and the receivers will know that they are authentic, because the DKIM option makes it impossible for unsolicited people to forge your e-mail addresses.
