I mean that we already have SMTP headers for metadata. Such as in-reply-to (no need to quote the whole mail at the bottom of yours) and obviously the sender (no need for an explicit signature), and you could use x-face if you needed something fancier or, if your company really really needs to remind everyone how social they are at every message, you could have added an x-coprorate-blurb custom header, etc. Whatever, emails these days are nothing more than an archaic last resort password reset protocol.
