The website does have unsubscribe link at
http://hadoop.apache.org/mailing_lists.html#User for every list. Did
you try mailing after clicking on the link? Did it not work?
And every email the list sends out, has a "from" address in it you can
refer back on the same page. Personally I like it if the list doesn't
prefix its name to every email subject.
