I also put:

(setq nnmail-extra-headers gnus-extra-headers)

. The purpose I wanted is achieved, but *only* once the article
has been saved on disk. When I enter the nntp gnu.emacs.gnus newsgroup, 
all the articles have the 'From' header in place of the 'Newsgroups' header.
Then ,if I copy an article in another group and then open it again, I see the
'Newsgroups' header correctly displayed. It's strange?

Thanks,
