To fight email spoofing, a group of leading organizations came together to collaborate on a method to combat email spoofing at internet-scale.
Email Spoofing is a method where the sender makes it appear that the message originated from someone or somewhere and not from the actual source. It is a popular method used in phishing and spam campaigns because unsuspecting people will open emails, thinking that they came from known or reliable sources.
Organizations can stop spoof emails impersonating as them from reaching their customer’s inbox or junk/bulk folder by enabling DMARC.
