DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email by using an e-signature. When DomainKeys Identified Mail is enabled for a certain domain name, a public cryptographic key is published to the global DNS database and a private one is stored on the email server. If a new message is sent, a signature is generated using the private key and when the message is delivered, that signature is checked by the POP3/IMAP server using the public key. In this way, the recipient can easily distinguish if the message is genuine or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email has been modified on its way as well, so DKIM can also be used to make sure that the sent and the received email messages are identical and that nothing has been attached or removed. This email authentication system will enhance your email security, since you can validate the legitimacy of the important email messages that you receive and your partners can do the same with the email messages that you send them. Depending on the particular email service provider’s adopted policies, an email that fails to pass the test may be erased or may emerge in the receiver’s mailbox with a warning alert.

DomainKeys Identified Mail in Cloud Hosting

If you obtain one of the Linux cloud hosting packages that we’re offering, the DomainKeys Identified Mail functionality will be enabled by default for any domain name that you register under your website hosting account, so you won’t have to create any records or to enable anything manually. When a domain name 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 name will be handled by our cloud web hosting platform), a private cryptographic key will be issued immediately on our email servers and a TXT resource record with a public key will be sent to the DNS system. All email addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as periodic newsletters, they will reach their target destination and the receivers will be sure that they are legitimate, since the DomainKeys Identified Mail feature makes it impossible for unauthorized individuals to spoof your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

All necessary DKIM records will be created automatically by our cloud platform when you add a domain name as hosted in your semi-dedicated server account, so if you choose to order a semi-dedicated server package, you will not need to set up anything to be able to take advantage of the email authentication system. The domain should use our name servers so that its DNS resource records can be managed by us and as long as this prerequisite is fulfilled, a private key will be created on our mail servers and a public key will be sent to the global Domain Name System by a special TXT resource record. All addresses that you create with the domain name will be protected by DomainKeys Identified Mail, which will make it impossible for third parties to fake any email address. Both you and your colleagues or clients can take advantage of this service, as it will ensure a much higher protection level for your e-communication.
