If the answer is "not very", that tells me that both x= and fixed time
limits are a mistake.
That may well be true, but the credibility of a DKIM signature
in a court, or a year after signing, is explicitly not in scope
of this WG according to our charter.
I hope the credibility of a signature to a recipient is in scope, which is
why I'm trying to figure out how x= or fixed time limits affect that
credibility.
