Anyone know how to use the killfile in Mozilla Thunderbird? Now I've
downloaded a 'proper' newsreader and am no longer using Google Groups
I'd like to be rid of this idiot once and for all.

menu item 'Tools' then filters. If @From' equals 'some email address'
then 'delete

This works for me. Just add for each email address you wish not to see.
