DomainKeys Identified Mail, or DKIM, is a system for validating the authenticity of an email message by using an e-signature. When DKIM is enabled for a particular domain name, a public encryption key is published to the global Domain Name System and a private one is kept on the email server. When a new email is sent, a signature is issued using the private key and when the email is delivered, that signature is authenticated by the POP3/IMAP email server using the public key. Thus, the recipient can easily discern if the email is authentic 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 DKIM can also be used to ensure that the sent and the received email messages are identical and that nothing has been added or removed. This email authentication system will increase your email safety, as you can validate the authenticity of the important emails that you get and your colleagues can do likewise with the emails that you send them. Depending on the given mail service provider’s adopted policy, an email message that fails to pass the test may be erased or may be delivered to the recipient’s mailbox with a warning.

DomainKeys Identified Mail in Shared Web Hosting

The DomainKeys Identified Mail functionality is pre-activated for all domains that are hosted in a shared web hosting account on our cloud platform, so you won’t have to do anything on your end to activate it. The sole requirement is that the given domain name should be hosted in a hosting account on our end using our NS and MX records, so that the e-mail messages will go through our email servers. The private cryptographic key will be generated on the server and the TXT resource record, which includes the public key, will be published to the global DNS database automatically, so you will not have to do anything manually on your end in order to activate this option. The DomainKeys Identified Mail validation system will permit you to send trustable e-mail messages, so if you are sending offers or a newsletter to customers, for example, your emails will always reach their target viewers, whereas unsolicited third parties will not be able to forge your email addresses.
