DomainKeys Identified Mail, or DKIM, is a system for verifying the legitimacy of an email message using a digital signature. When DKIM is enabled for a particular domain, a public 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 delivered, the signature is authenticated by the incoming POP3/IMAP server using the public key. In this way, the receiver can easily discern if the email 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 edited 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 email validation system will heighten your email security, as you can confirm the legitimacy of the important email messages that you get and your associates can do likewise with the messages that you send them. Depending on the given email service provider’s policies, an email message that fails to pass the check may be removed or may end up in the receiver’s inbox with a warning notification.

DomainKeys Identified Mail in Shared Website Hosting

If you purchase any of the Linux shared website hosting that we are offering, the DomainKeys Identified Mail feature will be activated by default for any domain that you add to your shard hosting 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 in-house built Hepsia Control Panel using our MX and NS records (so that the email messages associated with this domain 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 global DNS database. All addresses set up with this domain name will be protected by DKIM, so if you send emails such as periodic newsletters, they will reach their target destination and the receivers will be sure that they are authentic, since the DomainKeys Identified Mail functionality makes it impossible for unauthorized persons to forge your email addresses.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail activated by default, so if you select a semi-dedicated package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the email authentication system will be set up automatically – a private cryptographic key on our mail servers for the electronic signature and a TXT record carrying the public key for the DNS database. Since the protection is set up for a particular domain name, all e-mail addresses created under it will carry a signature, so you won’t need to worry that the messages that you send may not be delivered to their destination address or that somebody may spoof any of your addresses and try to scam/spam people. This may be extremely important when you rely on e-communication in your business, as your colleagues and/or clients will be able to distinguish real emails from fake ones.
