Have you considered the implications of format=flowed (rfc2646)?  Specifically:

4.6.  Digital Signatures and Encryption

   If a message is digitally signed or encrypted it is important that
   cryptographic processing use the on-the-wire Format=Flowed format.
   That is, during generation the message SHOULD be prepared for
   transmission, including addition of soft line breaks, space-stuffing,
   and [Quoted-Printable] encoding (to protect soft line breaks) before
   being digitally signed or encrypted; similarly, on receipt the
   message SHOULD have the signature verified or be decrypted before
   [Quoted-Printable] decoding and removal of stuffed spaces, soft line
   breaks and quote marks, and reflowing.
