RFC 2369 <http://www.faqs.org/rfcs/rfc2369.html>

This essentially says that you add headers like this to every mail:

List-Help: <mailto:autoconf-request(at)gnu(dot)org?subject=help>
List-Post: <mailto:autoconf(at)gnu(dot)org>
List-Subscribe: <http://mail.gnu.org/mailman/listinfo/autoconf>,
<mailto:autoconf-request(at)gnu(dot)org?subject=subscribe>
List-Id: Discussion list for the autoconf build system <autoconf.gnu.org>
List-Unsubscribe: <http://mail.gnu.org/mailman/listinfo/autoconf>,
<mailto:autoconf-request(at)gnu(dot)org?subject=unsubscribe>
List-Archive: <http://mail.gnu.org/pipermail/autoconf/>

(There's isn't anything for FAQ, but there could be a link on the archive
page maybe.)

If a mail with these headers shows up in my mail client I get a link "This
message contains email list management information." that I can click on
and which in turn explains to me what an email list is and then allows me
to click on the URLs above. Very nice.
