DomainKeys Identified Mail, or DKIM, is a method for validating the authenticity of an email message using a digital signature. When DomainKeys Identified Mail is activated for a specific domain, a public cryptographic key is published to the global Domain Name System and a private one is stored on the email server. When a new message is sent, a signature is generated using the private key and when the email is received, that signature is verified by the POP3/IMAP email server using the public key. In this way, the recipient can easily know if the message is legitimate or if the sender’s email address has been forged. A discrepancy will occur if the content of the email message has been modified on its way as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the received messages are identical and that nothing has been attached or deleted. This validation system will strengthen your email safety, as you can verify the legitimacy of the important emails that you receive and your associates can do the exact same thing with the emails that you send them. Based on the particular email service provider’s policies, an email that fails the check may be erased or may show up in the receiver’s inbox with a warning alert.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a web hosting account on our cloud web hosting platform, so you will not have to do anything yourself to activate it. The only requirement is that the particular domain should be hosted in a website hosting account on our platform using our NS and MX records, so that the e-mails will go through our mail servers. The private encryption key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS system automatically, so you will not have to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail authentication system will permit you to send out trustable email messages, so if you are sending offers or a newsletter to customers, for example, your emails will always reach their target viewers, whereas unauthorized 3rd parties will not be able to spoof your email addresses.
