1) The signer can use the z= tags to save the header signing data.
Unfortunately, the verification algorithm, as it is currently designed,
does nothing with z=. I think z= needs to be reconsidered, as
I have noted awhile back (probably on ietf-mailsig).
Anyway, I think the positives outweigh the negatives.
It seems that a mailing list that mucks with a message is a good
test case for how DKIM survives, or addresses, such behavior.
This is where the challenge is, not with lists that just re-direct
messages without alteration (except maybe the addition of trace
fields and List-* fields).
