If we implement some sort of posting cookie, it should be bakable by any
user wishing to post, and work with every conceivable variety of OS and
mailer.
One scheme which comes to mind is to allow people to mail their posts
to "N+cypherpunks@*" where N is the number of non-whitespace characters
in the subject of the post, exclusive of Subject: and Re:.
People subscribing could then elect to receive only those posts where
N matched, or to receive all posts. While the N+cypherpunks addresses
would of course end up on spam lists, statistically, the spam would get
cut by a factor of around 20 for people who chose to filter.
This would have the following features.
1. It would be very simple to implement.
2. It would be end-user filtering, which people would be able to elect.
3 It doesn't require any complicated software on the list processing
end, and no software at all on the user end.
4. People who don't want to mess with it will never know it's there.
This is just one way to do it. I'm sure people will think up better
variations.
