Rated 4 out of 5 stars

Great add-on!
I tried it with thunderbird 2.0.0.19 on my freebsd 7.1 box, and it worked like a charm.
By the way, actually, it is possible to retract text emails only. and I hope that in the near future, will be also possible to retract mails with an attachment.
Together with this plugin I suggest to use the SimpleStatisics plugin that should be very useful for the TheundeRetract developers.
Cheers, bye
