This add-on is great.
It helps me tell if a message is spam or not, without opening it first.
Highly recommended

I get bombarded with spam email. This add-on allows me to preview the message without sending a return receipt. Then I can delete it after adding the sender to my filters.
It has helped me cut down on unwanted spam email.
