No, don't use these. Use X-BeenThere:. There are four or five headers in
use by different mailing list management software, that can be used for
filtering purposes. X-BeenThere is the one Mailman uses.

Some mail software, such as Evolution, automatically recognizes these
headers, and can thus know that it's list mail. For instance, in
Evolution, you can do Tools->Create Filter From Message->Filter on
Mailing List, and it'll do the right thing.

Host-independent  isn't really what you're looking for. If a mailing
list moves to another host, chances are you will have to change things
anyway. Besides, that's the reason you use aliases like
"lists.copyleft.no"
