I have come across certain scenarios which confuses me on how it is possible to manipulate email headers.
The person who received an email(A) from person (B), forwarded me (C) the email as Original attachment.
While analysing the email headers I am seeing the From property of the email header is showing C instead of B.
While analysing the email headers, I am seeing the To property of the email header is showing B instead of showing A.
How is this made possible and is there a way to validate the right sender/receiver?
