DomainKeys Identified Mail, or DKIM, is a method for validating the genuineness of an email using an e-signature. When DKIM is activated for a certain domain, a public encryption key is published to the global DNS database and a private one is stored on the mail server. When a new email message is sent, a signature is issued using the private key and when the message is delivered, the signature is authenticated 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 address has been spoofed. A mismatch will appear if the content of the email message has been modified in the meantime as well, so DomainKeys Identified Mail can also be used to ensure that the sent and the delivered emails are identical and that nothing has been attached or deleted. This authentication system will increase your email security, since you can verify the genuineness of the important emails that you receive and your associates can do the same with the messages that you send them. Based on the given email provider’s adopted policy, an email message that fails the check may be removed or may end up in the receiver’s mailbox with a warning symbol.

DomainKeys Identified Mail in Cloud Hosting

The DomainKeys Identified Mail option is activated by default for all domain names that are hosted in a cloud hosting account on our cloud hosting platform, so you won’t need to do anything on your end to activate it. The sole condition is that the particular domain name should be hosted in a hosting account on our platform using our MX and NS records, so that the e-mail messages 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 DNS database automatically, so you won’t have to do anything manually on your end in order to enable this functionality. The DKIM authentication system will permit you to send credible e-mail messages, so if you are sending offers or a newsletter to customers, for example, your email messages will always reach their target audience, while unsolicited third parties won’t be able to spoof your email addresses.
