The Reply-to-list option (and other list submenu) should be active if
any of these match (see camel/camel-mime-utils.c):

        { "List-Post", "[ \t]*<mailto:([^@>]+)@?([^ \n\t\r>]*)" },
        { "List-Id", "[^<]*<([^\\.>]+)\\.?([^ \n\t\r>]*)" },
        { "Mailing-List", "[ \t]*list ([^ ]+)@?([^ \n\t\r>;]*)" },
        { "Originator", "[ \t]*([^ ]+)@?([^ \n\t\r>]*)" },
        { "X-Mailing-List", "[ \t]*<?([^@>]+)@?([^ \n\t\r>]*)" },
        { "X-Loop", "[ \t]*([^ ]+)@?([^ \n\t\r>]*)" },
        { "X-List", "[ \t]*([^ ]+)@?([^ \n\t\r>]*)" },
        { "Sender", "[ \t]*owner-([^ ]+)@?([^ @\n\t\r>]*)" },
        { "Sender", "[ \t]*([^ ]+)-owner ?([^ @\n\t\r>]*)" },
        { "Delivered-To", "[ \t]*mailing list ([^ ]+)@?([^ \n\t\r>]*)" },
        { "Return-Path", "[ \t]*<?owner-([^@>]+)@?([^ \n\t\r>]*)" },
        { "X-BeenThere", "[ \t]*([^ ]+)@?([^ \n\t\r>]*)" },
        { "List-Unsubscribe", "<mailto:(.+)-unsubscribe@([^ \n\t\r>]*)" },

Just to double-check, I sent myself two copies of your latest message,
both with and without the List-Post: header:

dwmw2 ~/Maildir/.lists.evo/cur $ cat 1279274987.H637206P5247.twosheds.infradead.org:2, | sed -e '/^List-Post: 
/d'  -e 's/^Subject: .*/Subject: test with no LP/' | /usr/lib/sendmail dwmw2 infradead org
dwmw2 ~/Maildir/.lists.evo/cur $ cat 1279274987.H637206P5247.twosheds.infradead.org:2, | sed -e 's/^Subject: 
.*/Subject: test with LP/' | /usr/lib/sendmail dwmw2 infradead org

When I view them both in my INBOX, the 'Reply to list' option is enabled
for both of them. For one it goes to the list, for the other it doesn't
find the List-Post: header and thus falls back to replying to all.

I'd send you the same messages to test, but ISTR your mail software is
broken and would silently delete both of them because it thinks it's
already seen them?

(I say "broken" because of all the fun I can have with it. I can send
messages to the list that I know your system will delete without you
seeing them -- and I when I am directly Cc'd on messages which were also
sent to the list, I can quickly send you a different message with the
same Message-Id:, thus ensuring that you never receive the real list
message :)

That's what I was looking for; thanks. Do you do this often enough that
you really want a third toolbar button, and the existing drop-down
choice on the 'Group Reply' button isn't sufficient?

Much as I hate to suggest yet another reply option -- do we want a
'Reply to List-Post: and Cc: headers; not From:'?

If you're not aware of the new 'Group Reply' button, it's shown and
described at the bottom of http://david.woodhou.se/reply-to-list.html
