DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email by using an electronic signature. When DKIM is enabled for a certain domain, a public cryptographic key is published to the global DNS system and a private one is kept on the email server. When a new email is sent, a signature is generated using the private key and when the email message is delivered, that signature is checked by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily distinguish if the message is genuine or if the sender’s 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 ensure that the sent and the received emails are identical and that nothing has been attached or removed. This email validation system will boost your email safety, as you can verify the authenticity of the important emails that you get and your colleagues can do the same with the emails that you send them. Depending on the particular mail service provider’s policy, an email that fails to pass the check may be removed or may show up in the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Cloud Web Hosting

In case you host a domain name in a cloud web hosting account with our company, all the needed records for using the DomainKeys Identified Mail option will be set up by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia hosting Control Panel, as long as your domain also uses our NS records. A private cryptographic key will be generated on our email servers, while a public key will be published to the global DNS system automatically by using the TXT resource record. Thus, you won’t have to do anything manually and you will be able to take advantage of all the benefits of this email authentication system – your messages will be sent to any target audience without being rejected and no one will be able to send email messages faking your addresses. The latter is truly important in case the nature of your online presence involves sending out periodic newsletters or offers via email to potential and current clients.

DomainKeys Identified Mail in Semi-dedicated Servers

The DomainKeys Identified Mail functionality is included by default with any domain that’s registered through a semi-dedicated server account with our company. The domain must also use our name servers, so that its DNS resource records are managed by our platform. The latter makes it possible for a special TXT record to be set up, which is actually the public encryption key that verifies if a specific email message is legitimate or not. Such a record is set up once a domain name is registered in a semi-dedicated account through the Hepsia Control Panel and in the meantime, a private key is generated on our email servers. If you use our email and web hosting services, your email messages will always reach their target viewers and you won’t need to worry about unsolicited parties spoofing your email addresses for spamming or scamming purposes, which is something quite important in case you use email messages to contact your business collaborators.
