	If you're going to be serious about anonymizing something, you 
have no choice but to strip everything but certain specific headers 
that you know to be clean.

	You would certainly have to remove "Message-Id:" and regenerate 
locally on the anonymizing mail server.  I'd have to talk to certain 
people I know in the anonymous remailer community to see which others 
would also have to be removed, and find out the reasoning behind that.
