Mailing List Headers

It would be great if all mailing lists included the headers described in RFC 2369 and RFC 2919. Qurb uses these headers (and some others) to allow mailing lists to be an Approved Sender. Most modern mailing list managers (MLMs) support these headers, but not every list administrator configures things correctly. There are also some old lists which still don't use the standard headers.

I hope the various anti-spam laws under consideration will require these mailing list headers for all bulk mail. While it won't stop the hard core spammer, it will make it easier to get off (or block) the lists of legal but sleazy bulk mailers.
