DomainKeys Identified Mail, or DKIM, is a method for verifying the legitimacy of an email message using a digital signature. When DKIM is activated for a particular domain name, a public encryption key is published to the global DNS system and a private one is kept on the email server. When a new email message is sent, a signature is generated using the private key and when the email is received, the signature is authenticated by the incoming POP3/IMAP server using the public key. Thus, the receiver can easily know if the email is authentic or if the sender’s address has been forged. A mismatch will appear if the content of the email has been changed on its way as well, so DomainKeys Identified Mail can also be used to make sure that the sent and the delivered messages are identical and that nothing has been added or removed. This email authentication system will strengthen your email security, as you can confirm the genuineness of the important email messages that you receive and your colleagues can do the exact same thing with the email messages that you send them. Based on the particular email provider’s adopted policy, an email message that fails the test may be erased or may enter the recipient’s inbox with a warning notification.

DomainKeys Identified Mail in Shared Website Hosting

If you host a domain name in a shared website hosting account with us, all the compulsory records for using the DomainKeys Identified Mail feature will be added by default. This will happen the moment you add the domain name in the Hosted Domains section of the Hepsia hosting Control Panel, on the condition that your domain also uses our NS records. A private encryption key will be created on our mail servers, whereas a public key will be published to the global DNS database automatically using the TXT record. Thus, you will not have to do anything manually and you will be able to make use of all the benefits of this authentication system – your emails will be sent to any destination without being disallowed and no one will be able to send email messages forging your e-mail addresses. The latter is really important if the essence of your online presence suggests sending out periodic newsletters or offers via email to prospective and existing customers.
