DKIM, which is an acronym for DomainKeys Identified Mail, is an email validation system, which hinders email addresses from being spoofed and email content from being meddled with. This is achieved by attaching an e-signature to each and every email sent from an address under a certain domain. The signature is generated based on a private encryption key that is available on the sending server and it can be validated by using a public key, which is available in the global Domain Name System. Thus, any message with edited content or a spoofed sender can be spotted by mail service providers. This approach will heighten your worldwide web safety noticeably and you’ll know for sure that any message sent from a business collaborator, a banking institution, etc., is genuine. When you send emails, the recipient will also be sure that you are indeed the one who has sent them. Any email message that turns out to be fake may either be tagged as such or may never show up in the recipient’s mailbox, depending on how the particular provider has chosen to handle such messages.
