DKIM, which stands for DomainKeys Identified Mail, is an email validation system, which obstructs email addresses from being spoofed and email content from being manipulated. This is done by attaching an electronic signature to each email sent from an email address under a particular domain. The signature is issued on the basis of a private cryptographic key that is available on the outgoing server and it can be verified by using a public key, which is available in the global DNS database. Thus, any email message with edited content or a forged sender can be recognized by email providers. This method will enhance your online security dramatically and you will be sure that any message sent from a business ally, a banking institution, etc., is genuine. When you send messages, the receiver will also know for sure that you are indeed the one who has sent them. Any mail that turns out to be phony may either be tagged as such or may never reach the receiver’s inbox, based on how the given provider has chosen to deal with such messages.
