The file attached to #21 and #22 should be identical. I attached #21, and Scott attached #22 from files I emailed him. The files on #21 and #22 were captured before being sent. Neither is post mailing. I sent these with twisted, which I think does *not* fold lines... but I could be wrong.

I looked at my live.com test address. It has a "view message source" option, that opens a new window and shows the message with minimal formatting. I've never much trusted such pages to show the "real" source... Anyway, when I compared the DKIM header in what I sent to what live.com showed, they match. They have the same folding. I hesitate to draw too much from that, but it would seem to mean that no additional folding happened between signing and delivery.
