DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email message using a digital signature. When DKIM is activated for a certain domain name, a public key is published to the global Domain Name System and a private one is kept on the email server. If a new email message is sent, a signature is generated using the private key and when the email message is received, that signature is ‘scanned’ by the incoming server using the public key. In this way, the recipient can easily discern if the message is legitimate or if the sender’s email address has been spoofed. A mismatch will occur if the content of the email message has been modified in the meantime as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been added or deleted. This email authentication system will enhance your email safety, as you can verify 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 given mail service provider’s policy, a message that fails to pass the test may be deleted or may reach the recipient’s inbox with a warning alert.

DomainKeys Identified Mail in Web Hosting

When you order any of the Linux web hosting that we’re offering, the DomainKeys Identified Mail functionality will be activated by default for any domain name that you register under your hosting account, so you will not have to set up any records or to do anything manually. When a domain name is added in the Hosted Domains section of our in-house developed Hepsia Control Panel using our MX and NS records (so that the emails associated with this domain will be handled by our cloud platform), a private key will be generated immediately on our email servers and a TXT record with a public key will be sent to the global DNS system. All email addresses set up with this domain name will be protected by DomainKeys Identified Mail, so if you send email messages such as periodic newsletters, they will reach their target audience and the recipients will know that the messages are genuine, as the DomainKeys Identified Mail option makes it impossible for unauthorized individuals to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

When you select any of the semi-dedicated servers that we offer, you will be able to use the DomainKeys Identified Mail protection service with any domain that you register through your brand new semi-dedicated server account without any manual intervention, as our cutting-edge cloud web hosting platform will create all the obligatory records automatically, on the condition that the domain name uses our name servers. The latter is required for a TXT resource record to be created for the domain, as this is how the public encryption key can become available in the global DNS system. The private key will also be added automatically to our mail servers, so every time you send a new message, it will carry our system’s e-signature. The number of spam emails keeps rising every year and rather often counterfeit email addresses are used, but if you make use of our hosting services, you and your customers or partners won’t have to worry about that.
