DomainKeys Identified Mail, or DKIM, is a system for verifying the authenticity of an email by using a digital signature. When DKIM is activated for a particular domain name, a public encryption key is published to the global DNS database 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 message is received, that signature is authenticated by the POP3/IMAP email server using the public key. In this way, the receiver can easily tell if the message is legitimate or if the sender’s address has been spoofed. A discrepancy will appear if the content of the email message has been changed in the meantime 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 removed. This email authentication system will increase your email security, since you can verify the legitimacy of the important email messages that you get and your associates can do the same with the email messages that you send them. Depending on the given email service provider’s adopted policy, an email message that fails the check may be deleted or may enter the receiver’s mailbox with a warning sign.

DomainKeys Identified Mail in Web Hosting

You will be able to get the most out of DomainKeys Identified Mail with each Linux web hosting packages that we’re offering without needing to do anything in particular, as the necessary records for using this email authentication system are created automatically by our web hosting platform when you add a domain to an active web hosting account using the Hepsia Control Panel. If the given domain name uses our NS records, a private encryption key will be generated and kept on our mail servers and a TXT record with a public key will be sent to the global DNS database. In case you send out periodic messages to customers or business partners, they will always be received and no unauthorized person will be able to spoof your email address and make it look like you have composed a particular email message.
