DKIM, which is an abbreviation for DomainKeys Identified Mail, is an email validation system, which stops email addresses from being forged and email content from being modified. This is done by adding a digital signature to every email message sent from an email address under a particular domain. The signature is generated on the basis of a private cryptographic key that is available on the outgoing SMTP email server and it can be verified using a public key, which is available in the global DNS database. Thus, any email with edited content or a forged sender can be recognized by email providers. This technology will heighten your web security substantially and you will know for sure that any message sent from a business associate, a banking institution, etc., is authentic. When you send out emails, the recipient will also be sure that you are indeed the one who has sent them. Any email message that appears to be fake may either be labeled as such or may never appear in the receiver’s inbox, based on how the particular provider has decided to treat such email messages.
