Hace poco recibí un correo electrónico extraño. El correo electrónico tiene diferentes campos From
y Reply-To
. También tiene To
establecido en Undisclosed recipients
pero no es crucial.
Al principio pensé que era falso, pero luego leí esto publicación que menciona que el campo Received
no puede ser falsificado. Parece que lo recibido es correcto en el caso del correo electrónico del que estoy hablando:

¿Es posible falsificar el campo Received
de alguna manera, quizás utilizando técnicas avanzadas?
