DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email by using a digital signature. When DKIM is enabled for a given domain, a public key is published to the global DNS system and a private one is kept on the mail server. When a new message is sent, a signature is generated using the private key and when the email message is received, that signature is verified by the POP3/IMAP server using the public key. In this way, the recipient can easily know if the email message is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email has been edited in the meantime as well, so DKIM can also be used to ensure that the sent and the received messages are identical and that nothing has been added or erased. This email authentication system will heighten your email safety, as you can verify the genuineness 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 email provider’s adopted policies, an email that fails the test may be deleted or may end up in the receiver’s mailbox with a warning flag.
DomainKeys Identified Mail in Shared Web Hosting
When you order any of the shared web hosting service that we offer, the DomainKeys Identified Mail option will be activated by default for any domain that you add to your shared account, so you will not have to create any records or to enable anything manually. When a domain name is added in the Hosted Domains section of our custom-built Hepsia Control Panel using our NS and MX records (so that the emails related to this domain name will be handled by our cloud web hosting platform), a private cryptographic key will be generated instantly on our email servers and a TXT resource record with a public key will be sent to the Domain Name System. All email addresses created using this domain name will be protected by DKIM, so if you send out emails such as regular newsletters, they will reach their target audience and the receivers will know that the messages are legitimate, as the DomainKeys Identified Mail feature makes it impossible for unsolicited people to forge your e-mail addresses.
DomainKeys Identified Mail in Semi-dedicated Servers
The DomainKeys Identified Mail option is included by default with any domain name that’s added to a semi-dedicated server account with us. It should also use our name servers, so that its DNS records are handled by our platform. The latter makes it possible for a special TXT record to be set up, which is in fact the public encryption key that confirms if a specific email is authentic or not. Such a record is created when a new domain name is added to a semi-dedicated server account via the Hepsia Control Panel and at the same time, a private key is created on our mail servers. If you use our web and email hosting services, your emails will always reach their target viewers and you will not need to worry about unauthorized persons spoofing your addresses for spamming or scamming purposes, which is something really important in case you use email messages to touch base with your business collaborators.
