I still have no idea what headers you'd consider to be technical. Message-ID? Expires? (Don't tell me, it's not helpful.) >I'd be curious to learn why.

In any event, as we've now said several times, the Content-Type attack is specifically described in RFC 6376. I see that the perl and python DKIM modules sign the content-* headers by default.
