DKIM, which is short for DomainKeys Identified Mail, is a validation system, which prevents email addresses from being spoofed and email content from being modified. This is done by adding an e-signature to each and every message sent from an email address under a specific domain name. The signature is generated based on a private key that is available on the outgoing mail server and it can be verified with a public key, which is available in the global DNS database. Thus, any message with altered content or a forged sender can be recognized by mail service providers. This technology will enhance your web safety significantly and you’ll be sure that any email message sent from a business collaborator, a banking institution, and so on, is legitimate. When you send email messages, the receiver will also be sure that you are indeed the one who has sent them. Any email that appears to be bogus may either be tagged as such or may never end up in the receiver’s inbox, depending on how the given provider has chosen to deal with such emails.
