LJ responses aren't being sent to the Junk folder, they're being sent to the "LJ" folder, just where I want them =)

At the top of the preview panel however, there is a big friendly yellow line which says "Thunderbird thinks this message might be an email scam". Adding the LJ response address to my contacts list has allowed me to just see the pictures rather than clicking on "not a scam" then "show me the f*****g pictures". Still the "email scam" message is just a tiny bit annoying.
