Rewriting is a common cause of breaking DKIM signatures. There is a plethora of cases where they fail anyway, but in this case the message was a plain text message in us-ascii, so it's quite difficult to understand why signatures have been broken.My understanding is that the message was rewritten because it missed an explicit "Content-Transfer-Encoding: 7bit". I see two ways of fixing this with one liners:
Message rewriting is a fundamental operation. This concept has existed since the very beginnings of email, where message rewriting was common, as email transited between wildly different environments.
Over time, message rewriting became less and less common, as the common underlying platform, Internet/POSIX/SMTP, has displaced other, more exotic environments.
Still, header writing is still as valid today as it ever been. Any scheme that breaks because of it, is exactly this: broken. If DKIM gets broken when mail headers are writing and standardized, it's DKIM that's broken, fundamentally, and that's what should be fixed.
