Discounting whether disclaimers carry any worthwhile legal weight, technically
is it feasible to add a disclaimer to outgoing SMIME messages at the outgoing
server without breaking the signature ? The multipart nature of MIME suggests
that it is at least plausible to place the disclaimer in its own MIME boundary
such that it doesn't interfere with signed portions in the parts of the message
that originate at the client.
