Dear All, Can't we just go back to the way it was, with [$MAILING_LIST] in the subject line, re-write From: then sign the e-mail on the lists.archlinux.org server? That way DMARC and everyone's mail program could be made happy. Since we do not re-write the Subject: anymore I cannot separate the Arch list e-mail well anymore. Some (mobile) clients cannot mark or file mail as well as desktop clients can and everything ends up in one inbox. Just my 2 cents. Merry Christmas everyone!
