DomainKeys Identified Mail, or DKIM, is a system for checking the authenticity of an email using a digital signature. When DKIM is activated for a specific domain name, a public key is published to the global Domain Name System and a private one is stored on the email server. When a new email message is sent, a signature is generated using the private key and when the email message is delivered, that signature is validated by the incoming POP3/IMAP mail server using the public key. In this way, the receiver can easily distinguish if the email message is genuine or if the sender’s email address has been forged. A discrepancy will occur if the content of the email has been modified on its way as well, so DKIM can also be used to make sure that the sent and the received messages are identical and that nothing has been added or erased. This email authentication system will increase your email safety, as you can verify the genuineness of the important email messages that you receive and your associates can do likewise with the emails that you send them. Based on the given email service provider’s adopted policy, a message that fails the examination may be removed or may appear in the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Web Hosting

The DomainKeys Identified Mail functionality is activated 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 enable it. The only condition is that the particular domain should be hosted in a web hosting account on our platform using our NS and MX resource records, so that the email messages will go through our email 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 Domain Name System automatically, so you will not have to do anything manually on your end in order to enable this feature. The DKIM validation system will enable you to send credible e-mail messages, so if you’re sending a newsletter or offers to clients, for instance, your emails will always reach their target audience, while unsolicited third parties will not be able to forge your email addresses.
