Rated 5 out of 5 stars
I'm giving you 5 Stars because you have resolved the "Fwd:" addition, congratulations!
Still, I'm not going to use the add-on because I need the messages to be marked as read.

Works, but does not mark the original Emails as "forwarded". Please contact me on fb.com/biodanyell when you'll have resolved that, then I'll change my rating.This review is for a previous version of the add-on (1.1.1).
