I have not yet had the time to invest to scientifically prove that the spammers
got my address from gleaning the list or archives. But it might be fun to do.
Get an account at spamgourmet, or equiv. Sign up to a series of lists, having all list
submissions go to unique-to-list throw-away addrs. Post a few messages,
and then close down the mailman account, after the messages go out.
Watch the throw-away accounts, and see if they get spammed. I **have**
verified that the w3.org mailing list is responsible for one throw-way
getting spammed. (and big-time, at that!)

I totally agree. We need to filter out *all* addresses from the outgoing messages,
to protect folks who like to include their email in message trailers and sigs, or
who quote other emails from other users, and get them spammed, also.
Obfuscation can/will be overcome and is not a solution.
