My understanding of a DKIM signature is that it's the same idea as the clip
at the end of a political ad where the candidate says "I'm Joe Blow and I
approved this message". The signature doesn't mean that the signer wrote
the message or originated it, it just means that the signer approved it,
and you can blame the signer if you don't like it.
Yes. Yes! Just like when I sign a cheque dated April 1, 2006, my signature
is good for that specific cheque written on that date. You cannot apply that
signature to any other cheque I might have written, on April 1 or on any
other date.
?
And you can't guarantee that I might be alive at any future date to stand up
in court and verify the signature. The validity of the signature is from
when I wrote the cheque until the recipient cashed it at the bank.
Actually the validity of check is from when you wrote it until 60 days
unless it has been checked in the bank sooner. In fact for some checks
the validity is even smaller then 60 days (it is usually written on the
check) while for others its longer.
