DomainKeys Identified Mail, or DKIM, is a system for confirming the legitimacy of an email by using an e-signature. When DomainKeys Identified Mail is enabled for a certain domain, a public encryption key is published to the global Domain Name System and a private one is stored on the email server. When a new email is sent, a signature is generated using the private key and when the email message is received, the signature is verified by the incoming POP3/IMAP mail server using the public key. Thus, the recipient can easily tell if the email message is authentic or if the sender’s address has been spoofed. A mismatch will appear if the content of the email message has been altered 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 added or removed. This email authentication system will increase your email security, since you can confirm the authenticity of the important emails that you receive and your associates can do the exact same thing with the emails that you send them. Depending on the given mail service provider’s adopted policy, an email that fails to pass the check may be removed or may reach the receiver’s inbox with a warning notification.
DomainKeys Identified Mail in Cloud Website Hosting
The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a cloud website hosting account on our cloud hosting platform, so you will not need to do anything on your end to activate it. The only requirement is that the particular domain name should be hosted in a web hosting account on our platform using our MX and NS resource records, so that the emails will go through our email servers. The private cryptographic key will be generated on the server and the TXT record, which contains the public key, will be published to the DNS database automatically, so you will not need to do anything manually on your end in order to enable this option. The DKIM email validation system will permit you to send trustworthy e-mail messages, so if you are sending a newsletter or offers to clients, for instance, your emails will always reach their target destination, while unauthorized 3rd parties won’t be able to forge your email addresses.
