DomainKeys Identified Mail, or DKIM, is a system for confirming the authenticity of an email using a digital signature. When DKIM is enabled for a particular domain name, a public encryption key is published to the global DNS database and a private one is kept on the email server. When a new message is sent, a signature is generated using the private key and when the message is delivered, that signature is validated by the incoming POP3/IMAP email server using the public key. In this way, the receiver can easily recognize if the message is legitimate or if the sender’s address has been forged. A discrepancy will appear if the content of the email has been edited 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 deleted. This email validation system will boost your email security, as you can verify the legitimacy of the important emails that you get and your colleagues can do the same with the emails that you send them. Based on the given mail service provider’s policy, a message that fails the examination may be erased or may show up in the recipient’s inbox with a warning notification.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail functionality is enabled by default for all domain names that are hosted in a hosting account on our cloud hosting platform, so you won’t have to do anything yourself to enable it. The only requirement is that the particular domain name should be hosted in an account on our platform using our NS and MX records, so that the emails will go through our mail servers. The private encryption key will be created on the server and the TXT resource record, which includes the public key, will be published to the global DNS database automatically, so you won’t have to do anything manually on your end in order to enable this option. The DKIM validation system will permit you to send credible e-mail messages, so if you are sending a newsletter or offers to customers, for instance, your email messages will always reach their target destination, while unauthorized 3rd parties will not be able to spoof your email addresses.
