Well, in my fairly ancient copy of exmh, any message with such headers causes an additional menu to appear: List... help unsubscribe owner subscribe archive id post Clicking on any of these takes you to the webpage referenced by the header. (It looks like it's just generating menu entries for whatever "List-foo" headers it finds; the behavior isn't real helpful for headers that don't contain URLs, but most of these do.) Whether there's anything mass-market that knows about these headers, I dunno, but it's not like the spec hasn't been out there plenty long enough: ftp://ftp.rfc-editor.org/in-notes/rfc2369.txt regards, tom lane
