Cybercriminals are known to spoof email addresses (impersonate a managing director, for example) in the hope that they are delivered to someone’s inbox. If DMARC is turned on, you will significantly improve the chances of your emails being delivered to the recipient’s inbox whilst making it more difficult for cybercriminals to impersonate you. As the email arrives at the recipient {behind the scenes}, a request is sent to authenticate who has sent the email. Once authenticated, it will enable the recipient to see the contents of the email. If it doesn’t receive the authentication key, you will be prompted with several options. Most likely that a spoof email will be rejected and end up in your spam quarantine or junk folder.
