Rated 5 out of 5 stars

This is awesome ,I've discovered that if you receive a forwarded email from Outlook when using thunderbird by default it keeps the FW: in the email, this means that outlook clients interpret this as a new thread.

Clean Subject removes the FW: (as per outlook) and this means that for people on outlook you get a proper continous thread
and not so many (i.e. NO) broken threads!

Great stuff!!

Cheers
