Thanks so much, I haven't updated my rules for years, since Squirrelmail stopped being all that useful. I am sure you are familiar with AvelSieve, any chance we'll see that kind of polish on this addon? Perhaps an open source license would help get it there? Any way, THANK YOU for your work, really appreciated!!
EDIT: oh my goodness I just found the extra tools when clicking off the Source button. Nice!!
This review is for a previous version of the add-on (0.2.0).
