DomainKeys Identified Mail (DKIM) is an email validation system used to verify that an email has been sent by an authorized individual or mail server. An e-signature is added to the header of the email message using a private encryption key. When the email is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and whether the content has been altered in any way. The main task of DKIM is to prevent 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 or financial institution, for example, but the signature doesn’t correspond, you will either not receive the message at all, or you will receive it with an alert that most likely it is not genuine. It depends on email providers what exactly will happen with an email message that fails the signature check. DKIM will also offer you an added layer of safety when you communicate with your business partners, for instance, since they can see for themselves that all the email messages that you exchange are legitimate and have not been tampered with on their way.

DomainKeys Identified Mail in Hosting

If you purchase any of the Linux hosting that we’re offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain that you add to your 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 MX and NS resource records (so that the email messages related to this domain will be handled by our cloud hosting platform), a private encryption key will be generated right away on our email servers and a TXT resource record with a public key will be sent to the DNS database. All addresses set up with this domain name will be protected by DKIM, so if you send out email messages such as periodic newsletters, they will reach their target destination and the recipients will be sure that the messages are authentic, as the DKIM feature makes it impossible for unauthorized persons to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All mandatory DomainKeys Identified Mail records will be created automatically by our cloud hosting platform when you add a domain as hosted in your semi-dedicated server account, so in case you decide to purchase a semi-dedicated plan, you won’t have to configure anything to be able to use the email authentication system. The domain must use our name servers so that its DNS records can be managed by us and as long as this requirement is satisfied, a private encryption key will be created on our email servers and a public key will be added to the DNS database by a special TXT resource record. All addresses that you create with the domain name will be protected by DKIM, which will make it impossible for third parties to fake any email address. Both you and your associates or customers can benefit from this feature, as it will ensure a higher level of protection for your electronic communication.
