I would like to suggest the implementation of new filters:

Forward message as plain text
Forward message as MIME attachment

Both filters are important to allow automated spam report to systems like SpamCop.net that are unable to "understand" the existing forwarding filter available for Thunderbird because they are forwarded as HTML messages. The existing Redirect filter does not works either.

This review is for a previous version of the add-on (1.2.0).
