It's better because:

* The List-ID header appears only in messages from the list, and in
every message from the list.

* The List-ID header should theoretically never change, even if the
mailing list address changes (which can happen if, e.g., it moves to be
hosted by a different server).

* The list E-mail address can appear in different headers (From, To, CC,
et cetera - sometimes depending on the mailing list, sometimes just
depending on the particular mail), and it's harder to properly filter on
multiple headers than on just one.

* In some cases (I haven't figured them all out yet), the list E-mail
address may not appear in the message at all.

* If you post to a mailing list, and someone hits Reply All on your
post, you will get two copies of the reply (unless your mail provider
filters one out, which has disadvantages). Both copies will include the
list's E-mail address somewhere, but only one of them actually came
through the list, so only one of them should be caught by the filter -
and only one of them will have the List-ID header.

That depends on your mail client. I know how to do it in Thunderbird 2,
and it's almost certainly very similar in current Thunderbird / Icedove,
but I don't have a functional Icedove instance nearby to give exact

That's... really weird, because your User-Agent header reads:

Mozilla/5.0 (X11; Linux x86_64; rv:24.0) Gecko/20100101 Icedove/24.6.0

Which not only mentions the absolutely most current release version of
Icedove - even though Outlook Express hasn't seen a new release in years
last I heard - but also claims that you're using 64-bit Linux. (And
Outlook Express barely runs on modern Windows AFAIK, much less on
