The lib email parse problem...

[叮叮当当]

supose a email part like this:

Content-Type: Multipart/Alternative;
boundary="Boundary-=_iTIraXJMjfQvFKkvZlqprUgHZWDm"


--Boundary-=_iTIraXJMjfQvFKkvZlqprUgHZWDm
Content-Type: text/plain; charset="gb2312"
Content-Transfer-Encoding: 7bit

   abcd.
--Boundary-=_iTIraXJMjfQvFKkvZlqprUgHZWDm
Content-Type: text/html; charset="gb2312"
Content-Transfer-Encoding: quoted-printable

.................
--Boundary-=_iTIraXJMjfQvFKkvZlqprUgHZWDm--

the plain text is abcd, and the alternative content type is text/html,
i should prefer explain the html content, and i must not explaint the
two part ,so i want to get the boundary end.

thanks all.
