DomainKeys Identified Mail, or DKIM, is a method for checking the legitimacy of an email by using a digital signature. When DKIM is activated for a given domain name, a public key is published to the global DNS database and a private one is stored on the mail server. If a new email is sent, a signature is issued using the private key and when the email is received, the signature is verified by the incoming email server using the public key. In this way, the receiver can easily recognize if the message is authentic or if the sender’s address has been spoofed. 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 make sure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This validation system will heighten your email safety, since you can validate the authenticity of the important emails that you receive and your colleagues can do likewise with the messages that you send them. Based on the given mail service provider’s policies, an email that fails to pass the test may be removed or may appear in the recipient’s mailbox with a warning sign.

DomainKeys Identified Mail in Shared Web Hosting

If you host a domain in a shared web hosting account from our company, all the required records for using the DomainKeys Identified Mail functionality will be set up by default. This will happen the moment you add the domain in the Control Panel’s Hosted Domains section, on the condition that the domain also uses our NS records. A private encryption key will be created on our mail servers, while a public key will be added to the global Domain Name System automatically using the TXT record. In this way, you won’t need to do anything manually and you will be able to enjoy all the benefits of this validation system – your emails will be sent to any audience without being discarded and no one will be able to send out emails faking your e-mail addresses. The latter is pretty important if the type of your Internet presence involves sending out periodic offers or newsletters via email to potential and current customers.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated packages come with DomainKeys Identified Mail enabled by default, so if you pick a semi-dedicated server 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 email servers for the digital signature and a TXT record carrying the public key for the Domain Name System. As the protection is set up for a particular domain, all e-mail addresses created under it will carry a signature, so you will not have to worry that the emails that you send may not reach their target address or that somebody may forge any of your email addresses and try to spam/scam people. This may be very essential in case you rely on email communication in your business, since your associates and/or customers will be able to distinguish legitimate email messages from fake ones.
