DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email using an e-signature. When DomainKeys Identified Mail is enabled for a specific domain, a public cryptographic key is published to the global Domain Name System and a private one is kept on the email server. When a new email is sent, a signature is generated using the private key and when the email is received, that signature is validated by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily know if the email is genuine 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 DomainKeys Identified Mail can also be used to make sure that the sent and the received email messages are identical and that nothing has been added or deleted. This validation system will boost your email security, as you can verify the legitimacy of the important emails that you get and your partners can do the exact same thing with the emails that you send them. Based on the particular email provider’s adopted policies, an email that fails to pass the check may be removed or may end up in the receiver’s mailbox with a warning.
DomainKeys Identified Mail in Website Hosting
If you host a domain name in a website hosting account from us, all the compulsory records for using the DomainKeys Identified Mail functionality will be created by default. This will happen once you add the domain in the Hosted Domains section of the Hepsia Control Panel, as long as it also uses our NS resource records. A private key will be generated on our mail servers, whereas a public key will be added to the global DNS database automatically using the TXT resource record. Thus, you will not need to do anything manually and you will be able to take advantage of all the benefits of this email validation system – your messages will be sent to any target destination without being discarded and nobody will be able to send messages faking your addresses. The latter is rather important in case the essence of your online presence suggests sending out regular offers or newsletters via email to prospective and current customers.
