FAQ
I haven't had time to sit and poke at the offending mail server to see
if they react to the reply to: or the from: header. I'll have to mess
with that this weekend when traffic is lower on lour lists.

"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.
I can't believe they are doing this either but unless someone invents a
machine capable of perpetual motion in the next couple of years, I'll
probably still have a job. ;)

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.
This would probably work for us. I was throwing this out to the list to
see what other approaches existed than the ideas I had. It didn't occur
to me to just obscure the domain name. I'd be happy to help out with
either the coding or testing if you need the help.


Thanks for the great suggestions all.
