DomainKeys Identified Mail, or DKIM, is a system for validating the genuineness of an email message using an e-signature. When DomainKeys Identified Mail is enabled for a particular domain, a public key is published to the global Domain Name System and a private one is kept on the mail server. If a new email message is sent, a signature is issued using the private key and when the email is delivered, the signature is ‘scanned’ by the incoming POP3/IMAP mail server using the public key. In this way, the recipient can easily discern if the email message 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 modified on its way as well, so DKIM can also be used to ensure that the sent and the delivered email messages are identical and that nothing has been attached or removed. This email validation system will increase your email security, as you can confirm the authenticity of the important emails that you get and your colleagues can do likewise with the messages that you send them. Depending on the particular mail service provider’s adopted policies, a message that fails to pass the test may be erased or may emerge in the recipient’s mailbox with a warning flag.

DomainKeys Identified Mail in Cloud Web Hosting

The DomainKeys Identified Mail option is pre-enabled for all domains that are hosted in a cloud web hosting account on our cloud website hosting platform, so you won’t need to do anything on your end to turn it on. The sole requirement is that the particular domain should be hosted in an account on our platform using our MX and NS resource records, so that the email messages will go through our email servers. The private encryption key will be generated on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you won’t have to do anything manually on your end in order to enable this feature. The DKIM email validation system will enable you to send out credible email messages, so if you are sending offers or a newsletter to customers, for example, your emails will always reach their target viewers, while unauthorized third parties will not be able to forge your email addresses.
