The problem occurs when you don't get the in-list copy, either because
the list doesn't send copies to addresses in Cc/To, or because some
mail systems (gmail) treat the delayed in-list copy as a duplicate. In
this case you can't use list-id reliably.

I think it's unusual for lists to suppress in-list copies, except as
an option, so this is mostly a gmail problem. I had to rewrite my
sieve rules when I switched to  gmail, before that list-id worked just
fine.
