BTW, the whole DKIM thing does not protect the body of a mail because
for example the Content-type is not commonly included in the hash and
thus you can change the boundary in this header and then tweak the body.
TLR had a PoC within hours after the DKIM idea was original proposed.
It was a major failure not to use established MIME formats for that
thing (protecting headers would have been simple with MIME).
