DKIM, which stands for DomainKeys Identified Mail, is an email authentication system, which blocks email headers from being forged and email content from being modified. This is achieved by attaching a digital signature to each email sent from an email address under a given domain name. The signature is created on the basis of a private encryption key that’s available on the outbound SMTP email server and it can be validated with a public key, which is available in the global DNS database. In this way, any email with edited content or a forged sender can be identified by email providers. This technology will enhance your web safety significantly and you will be sure that any email sent from a business ally, a banking institution, and so on, is an authentic one. When you send email messages, the recipient will also be sure that you are indeed the one who has sent them. Any mail that appears to be bogus may either be tagged as such or may never end up in the receiver’s mailbox, based on how the given provider has chosen to cope with such messages.
