DKIM, which is an acronym for DomainKeys Identified Mail, is a validation system, which blocks email addresses from being spoofed and email content from being modified. This is achieved by attaching an electronic signature to every email sent from an email address under a certain domain name. The signature is issued on the basis of a private encryption key that’s available on the outgoing SMTP mail server and it can be verified using a public key, which is available in the global DNS database. In this way, any email with altered content or a spoofed sender can be spotted by mail service providers. This approach will heighten your web safety noticeably and you’ll know for sure that any e-mail message sent from a business ally, a bank, etc., is genuine. When you send email messages, the receiver will also be sure that you are indeed the one who has sent them. Any email message that turns out to be fraudulent may either be tagged as such or may never show up in the receiver’s inbox, based on how the given provider has chosen to cope with such email messages.
