DomainKeys Identified Mail, or DKIM, is a system for verifying the authenticity of an email by using a digital signature. When DomainKeys Identified Mail is enabled for a certain domain, a public cryptographic key is published to the global DNS database and a private one is kept on the mail server. If a new message is sent, a signature is generated using the private key and when the email message is delivered, the signature is verified by the POP3/IMAP mail server using the public key. Thus, the recipient can easily tell if the email is legitimate or if the sender’s address has been forged. A discrepancy will appear if the content of the email message has been altered on its way as well, so DKIM can also be used to make sure that the sent and the delivered email messages are identical and that nothing has been attached or erased. This email validation system will boost your email safety, as you can verify the authenticity of the important emails that you get and your colleagues can do the exact same thing with the messages that you send them. Based on the given email provider’s policies, an email message that fails to pass the test may be deleted or may show up in the receiver’s mailbox with a warning flag.

DomainKeys Identified Mail in Hosting

The DomainKeys Identified Mail option is enabled by default for all domain names that are hosted in a hosting account on our cloud servers, so you will not need to do anything yourself to activate it. The sole condition is that the particular domain should be hosted in an account on our platform using our NS and MX records, so that the email messages will go through our mail servers. The private key will be generated on the server and the TXT record, which contains the public key, will be published to the Domain Name System automatically, so you will not need to do anything manually on your end in order to enable this option. The DomainKeys Identified Mail validation system will permit you to send trustable e-mails, so if you are sending offers or a newsletter to clients, for instance, your email messages will always reach their target viewers, whereas unauthorized third parties won’t be able to spoof your email addresses.
