why no answer

[nussbaum at neurochem.u-strasbg.fr]

I have sent at least 10 messages by E-mail to the following 
address: jdevellis%neuro2.dnet at loni.ucla.edu and got no answer 
up to now. IS that address uncorrect?? at my computer I see always 
the message "posting"... but never "post sent". Can somebody help me ??
