Fair enough. The discussion drifted with the introduction of the SpamCop 
idea that bounce messages are evil. As you have shown, it is possible in 
many instances to refuse mail at the door; however, it's pretty unfeasible 
in many environments...

Well, this is an interesting point applicable to my specific suggestion. 
You are right that such a script would generate a lot of misdirected mail. 
In my experience in dealing with this issue, it's usually e-mail viruses 
that spoof legitimate addresses: most of the spam I see comes from junk 
addresses at junk domains. So it's not like you're bugging a *human*.

In any case, this specific idea was just a brainstorm for how we could 
use X-Bogofilter: headers to allow LKML subscribers to make their own 
filtering decision about the messages. Another idea is to divert junk mail 
to a second list which is for people that want to be real sure they don't 
miss patches.

A third choice is obviously to leave the problem alone and let bogofilter 
eat our patches ;)

Whichever route is taken, though, it looks like we might have to switch 
away from Majordomo soon, because SpamCop and Stuart MacDonald are going 
to bring an end to programs that automatically respond to mail.

Thanks,
Chase
