At the very least, you can do a message/rfc822 bodypart, and that should guarantee that the signature is not broken, assuming that there's no changes in whitespace encoding, etc....

However, I don't know how most MUAs would handle that in a signed message. A more intelligent encapsulation format should hopefully address that issue.

Agreed. I'm not sure how receiving MUAs would handle this. I know that a message/rfc822 MIME body part is how messages are forwarded (as attachments) so they should be ok. At least I can forward a message as a message/rfc822 MIME body part and then later strip away everything but the contents of the message/rfc822 MIME body part and the message will then be able to be validated again. I will play with forwarding an S/MIME signed / encrypted message and let you know what my MUAs (of choice) do with the message/rfc822 MIME body part.
