#  The equals character is encoded as =3D in quoted-printable.
#  If the encoding is truly 8bit, we won't see it in the MIME source
#  of the email.  Instead, we'll see the equals character unmodified.

#  The AddHeaderField will replace the header field if it
#  already exists.

#  That's it... send the email and the HTML and/or plain-text body
#  will not be encoded using quoted-printable or base64 -- it
#  will instead be sent unencoded as 8-bit characters.

#  mailman.RenderToMime:
