DKIM, which stands for DomainKeys Identified Mail, is a validation system, which blocks email addresses from being spoofed and email content from being meddled with. This is achieved by adding an e-signature to each and every email sent from an email address under a given domain. The signature is published on the basis of a private cryptographic key that’s 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 technology will boost your web safety immensely and you will know for sure that any e-mail message sent from a business ally, a bank, and so on, is authentic. When you send email messages, the recipient will also be sure that you are indeed the one who has sent them. Any email that turns out to be fake may either be marked as such or may never show up in the receiver’s mailbox, based on how the given provider has chosen to deal with such email messages.
