[ietf-dkim] Blocking improperly signed messages

[Damon]

Since you brought it up...

No mailing list (or other _ Spam_ ) corruption of an email in transit
_or just plain spam_ can do anything worse than change the delivery of
a legitimate _or purposely munged_, DKIM-signed email into the
delivery of a legitimate _or more likely illegitimate_ non-DKIM-signed
email.

 The volume of spam is now -- what-- 7 out of 10?
 Doesn't BAD=NOSIG seem, even a little, useless... Especially at the
cost of decoding it at our current volume levels?
