DomainKeys Identified Mail, or DKIM, is a method for confirming the authenticity of an email by using an e-signature. When DKIM is activated for a given domain, a public cryptographic key is published to the global DNS system and a private one is kept on the mail server. When a new email message is sent, a signature is issued using the private key and when the message is delivered, the signature is checked by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily know if the email is authentic or if the sender’s email address has been spoofed. A discrepancy will appear if the content of the email message has been changed 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 removed. This email validation system will enhance your email security, as you can confirm the authenticity of the important email messages that you get and your partners can do the same with the email messages that you send them. Based on the given email service provider’s policy, an email that fails the test may be erased or may appear in the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Shared Website Hosting

In case you host a domain in a shared website hosting account from our company, all the mandatory records for using the DomainKeys Identified Mail feature will be added by default. This will happen as soon as you add the domain name in the Hosted Domains section of the Hepsia hosting Control Panel, on the condition that the domain also uses our NS records. A private cryptographic key will be created on our email servers, whereas a public key will be added to the global DNS system automatically by using the TXT resource record. Thus, you won’t need to do anything manually and you’ll be able to take full advantage of all the benefits of this email validation system – your email messages will reach any target destination without being discarded and nobody will be able to send emails faking your e-mail addresses. The latter is rather important if the type of your Internet presence suggests sending periodic newsletters or offers via email to prospective and current clients.

DomainKeys Identified Mail in Semi-dedicated Hosting

Our Linux semi-dedicated hosting come with DomainKeys Identified Mail activated by default, so in case you select a semi-dedicated hosting package and you add a domain name using our name servers through your Hepsia Control Panel, the records needed for the 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. As the DKIM protection is set up for a particular domain, all email addresses created with it will carry a signature, so you won’t have to worry that the email messages that you send out may not reach their destination email address or that someone may forge any of your addresses and attempt to scam/spam people. This may be very important when you rely on e-communication in your business, as your colleagues and/or customers will be able to distinguish legitimate email messages from fake ones.
