Furthermore, DomainKeys is trivially defeated with a replay attack.
Send yourself the spam through the signing server.  Now you have a signed
spam that you can re-mail far and wide.  Of course, you can't mutate it,
which might increase the effectiveness of DCC and the like, but it still
means you can't *really* trust a properly-signed message.
