I want to filter every message that is sent to a mailing list, except those that begin (or just contain) "Re:"
In "Has the words" I've put.
subject:(mailing-list) subject:(-re)
However that will seem to pull out (archive) entire threaded messages where the first one is not a "Re:" But the responses are.
I basically just want replies to go to my mail mailbox, but archive the rest.
