help me get rid of this MIME crap

hey folks... I'm trying to get rid of a mime-attachment which is sent with  
every message from a certain user.

I want to blindly convert his multi/mixed to plain text

Here are the MIME headers:

MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="---- =_NextPart_000_01BCADA3.4B50EB00"


------ =_NextPart_000_01BCADA3.4B50EB00
Content-Type: text/plain; charset="us-ascii"
Content-Transfer-Encoding: quoted-printable

[The real message goes here]

------ =_NextPart_000_01BCADA3.4B50EB00
Content-Type: application/ms-tnef
Content-Transfer-Encoding: base64

[some attached file, entirely useless]


Any thoughts appreciated.

I don't get a lot of mail from him, so even an inefficient recipe would be OK.
