That's not sufficient. It requres adding a Newsgroups: header, ensuring that
there's a Subject: header, that the Date: header is valid and within an
acceptable range, and that there are no folded headers. Optionally there's
some other header frobbery to make one's chosen newsreader happier.

I did it in Perl because a thirty line script that does it Right was less
effort than contriving a series of parameters for formail that will break
depending on the phase of the moon.

Originally it was using procmail, but I eventually replaced it with Exim
Filter when I realised that there were starting to be enough Lovecraftian
horrors lurking in my dotfiles that I'd need special arcane protection to
log in.
