For French, you can use the LN list <ln@cnusc.fr>.

The best technology for French, in my view, is that of the Synapse company
(http://www.synapse-fr.com/), who developped the Word2000 spelling and
grammatical tools. I personnally use their tagger/lemmatiser ("Cordial
universités"), which is absolutely astounding in terms of accuracy -- I get
no royalties :-)
although I am not sure about which. You can contact Dominique LAURENT
<dlaurent@synapse-fr.com> for details.
