"Mr. Foot, meet Mr. Bullet." Make sure you cash any checks from
naughty.com immediately; one gets the feeling they're not going to be
around for very long.

Why not simply change all instances of @naughty.com in the author
headers to @naughty.invalid or @censored.invalid or something like
that? It's easy enough to create a custom Handler to do that kind of
thing, and should be safe, too. Since you're going to have to modify
Mailman in any case, I believe, this is the least intrusive way to do
it.

If the answer is "that would work for us", then I'll look at doing the
coding and documenting the installation process, unless somebody beats
me to it. :-) Gotta run....
