DKIM, which is an acronym for DomainKeys Identified Mail, is a validation system, which stops email addresses from being spoofed and email content from being meddled with. This is done by adding an electronic signature to every email message sent from an address under a particular domain name. The signature is generated on the basis of a private encryption key that’s available on the outbound mail server and it can be verified using a public key, which is available in the global DNS database. In this way, any message with edited content or a spoofed sender can be spotted by mail service providers. This technology will strengthen your worldwide web safety considerably and you will know for sure that any email sent from a business partner, a bank, and so on, is an authentic one. 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 counterfeit may either be labeled as such or may never reach the recipient’s inbox, depending on how the given provider has chosen to cope with such emails.
