While it's intended to recover DKIM2 signatures, if you unwind the changes you'll get the earlier version of the message so I'd expect you could verify S/MIME or PGP signatures too. >Mainly I'm asking about the design intent: is reconstruction meant to >be a feature other signature schemes could rely on that way, or is it >only an internal DKIM2 mechanism? I don't think we're going to make any promises about other signature schemes, but unless something strange is going on, I'd usually expect them to work.
