DKIM, which is an abbreviation for DomainKeys Identified Mail, is an authentication system, which obstructs email addresses from being forged and email content from being meddled with. This is done by attaching an electronic signature to each email message sent from an email address under a given domain name. The signature is issued on the basis of a private encryption key that’s available on the 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 changed content or a spoofed sender can be spotted by mail service providers. This method will heighten your worldwide web safety greatly and you will know for sure that any message sent from a business partner, a bank, and so on, is a legitimate one. When you send emails, the recipient will also be sure that you are indeed the one who has sent them. Any email message that appears to be counterfeit may either be labeled as such or may never be delivered to the recipient’s mailbox, based on how the particular provider has chosen to handle such messages.
