Hi,
nice work on the translation tool ! I tried it with the french language, so here's my result : http://pedrov.kwain.net/~pedrov/rcube/rcube_trans.txt
By the way, I think - and all french folks would probably agree - that a better translation for "Junk mail" is the french term "Pourriel", since "A trier" means "to sort" in french.
best regards,
