DKIM, which is short for DomainKeys Identified Mail, is an email validation system, which blocks email headers from being forged and email content from being modified. This is achieved by attaching an e-signature to every email message sent from an address under a certain domain. The signature is generated on the basis of a private cryptographic key that’s available on the outgoing server and it can be verified using a public key, which is available in the global Domain Name System. Thus, any message with changed content or a spoofed sender can be spotted by mail service providers. This approach will strengthen your worldwide web safety tremendously and you’ll be sure that any e-mail sent from a business collaborator, a bank, and so on, is genuine. When you send email messages, the recipient will also know for sure that you are indeed the one who has sent them. Any email message that appears to be bogus may either be tagged as such or may never enter the recipient’s mailbox, depending on how the given provider has decided to handle such email messages.
