DomainKeys Identified Mail (DKIM) is an email validation system used to confirm that an email message has been sent by an authorized email server or person. An e-signature is attached to the email message’s header by using a private key. When the message is received, a public key that’s available in the global Domain Name System is used to confirm who exactly sent it and whether its content has been modified in some way. The essential function of DomainKeys Identified Mail is to avert the widely spread spam and scam messages, 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 instance, but the signature does not match, you will either not receive the email message at all, or you will receive it with a warning alert that most likely it’s not a genuine one. It depends on email service providers what exactly will happen with an email that fails the signature check. DKIM will also supply you with an additional layer of protection when you communicate with your business associates, for example, as they can see that all the emails that you exchange are authentic and haven’t been modified in the meantime.

DomainKeys Identified Mail in Web Hosting

When you get any of the Linux web hosting that we offer, the DomainKeys Identified Mail option will be enabled by default for any domain that you register under your shared web hosting account, so you will not need to set up any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our NS and MX records (so that the emails related to this domain will be handled by our cloud web hosting platform), a private key will be created immediately on our mail servers and a TXT record with a public key will be sent to the global DNS database. All addresses set up with this domain will be protected by DKIM, so if you send out emails such as periodic newsletters, they will reach their target audience and the receivers will know that the messages are legitimate, as the DKIM option makes it impossible for unsolicited parties to forge your addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

All obligatory DomainKeys Identified Mail records will be set up automatically by our cloud platform when you add a domain as hosted in a semi-dedicated server account, so in case you decide to order a semi-dedicated plan, you will not need to set up anything to be able to take advantage of the email authentication system. The domain must use our name servers in order for its DNS records to be managed on our end and as long as this precondition is matched, a private key will be generated on our email servers and a public key will be published to the DNS system by a special TXT record. All addresses that you create using the domain name will be protected by DKIM, which will make it impossible for third parties to spoof any email address. Both you and your associates or clients can benefit from this functionality, since it will ensure a much higher level of security for your email communication.
