DomainKeys Identified Mail, or DKIM, is a method for verifying the legitimacy of an email message using an e-signature. When DKIM is activated for a specific domain, a public cryptographic key is published to the global DNS system and a private one is stored on the mail server. If a new email is sent, a signature is generated using the private key and when the message is received, the signature is validated by the incoming POP3/IMAP server using the public key. In this way, the receiver can easily distinguish if the message is authentic or if the sender’s email address has been forged. A mismatch will appear if the content of the email has been changed 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 deleted. This authentication system will heighten your email security, since you can validate the genuineness of the important emails that you get and your colleagues can do the exact same thing with the messages that you send them. Based on the given email service provider’s policies, an email message that fails to pass the check may be erased or may appear in the recipient’s inbox with a warning alert.
DomainKeys Identified Mail in Web Hosting
If you obtain any of the web hosting that we’re offering, the DomainKeys Identified Mail feature will be enabled by default for any domain name that you add to your web hosting account, so you won’t need to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain will be handled by our cloud platform), a private cryptographic key will be generated momentarily on our email servers and a TXT record with a public key will be sent to the global DNS system. All email addresses created with this domain will be protected by DomainKeys Identified Mail, so if you send out email messages such as regular newsletters, they will reach their target audience and the receivers will be sure that they are legitimate, because the DKIM functionality makes it impossible for unsolicited parties to spoof your addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
The DomainKeys Identified Mail feature is offered by default with any domain that is registered through a semi-dedicated server account with our company. It should 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 resource record to be created, which is actually the public encryption key that verifies if a given email is genuine or not. This record is created the moment a domain is registered in a semi-dedicated server account via the Hepsia Control Panel and at the same time, a private key is created on our email servers. If you use our email and web hosting services, your emails will always reach their target viewers and you won’t have to worry about unsolicited individuals using your addresses for scamming or spamming purposes, which is something very important when you use emails to touch base with your business collaborators.
