DomainKeys Identified Mail, or DKIM, is a system for validating the legitimacy of an email message by using an e-signature. When DomainKeys Identified Mail is enabled for a certain domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the mail server. When a new email message is sent, a signature is generated using the private key and when the email message is delivered, that signature is authenticated by the incoming POP3/IMAP email server using the public key. In this way, the recipient can easily know if the message is authentic or if the sender’s address has been spoofed. A mismatch will occur if the content of the email message has been changed in the meantime as well, so DKIM can also be used to ensure that the sent and the delivered emails are identical and that nothing has been added or removed. This email authentication system will heighten your email safety, as you can verify the authenticity of the important emails that you get and your colleagues can do likewise with the emails that you send them. Depending on the given mail service provider’s adopted policy, an email that fails to pass the test may be removed or may enter the recipient’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Website Hosting

If you buy one of the shared website hosting that we are offering, the DomainKeys Identified Mail functionality will be activated as standard for any domain name that you register under your shared account, so you will not have to create any records or to do anything manually. When a domain is added in the Hosted Domains section of our custom-developed Hepsia Control Panel using our MX and NS resource records (so that the email messages related to this domain will be handled by our cloud platform), a private cryptographic key will be issued instantaneously on our email servers and a TXT resource record with a public key will be sent to the DNS system. All addresses set up with this domain will be protected by DomainKeys Identified Mail, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will know that they are authentic, as the DKIM feature makes it impossible for unauthorized parties to spoof your addresses.

DomainKeys Identified Mail in Semi-dedicated Servers

The DomainKeys Identified Mail functionality comes by default with any domain that is added to a semi-dedicated server account with us. It must also use our name servers, so that its DNS resource records are handled by our platform. The latter makes it possible for a special TXT record to be created, which is in fact the public encryption key that verifies if a specific email message is authentic or not. Such a record is created when a domain is registered in a semi-dedicated server account through the Hepsia Control Panel and in the meantime, a private key is created on our mail servers. If you make use of our email and web hosting services, your messages will always reach their target destination and you will not need to worry about unauthorized individuals spoofing your addresses for scamming or spamming purposes, which is something quite important if you use emails to contact your business associates.
