You might find it easier to use a tool which strips MIME out of
your email and leaves behind plaintext.  There are four options
in the FAQ:

I wrote stripmime and use it, but any of them should work.  It
will only keep text/plain sections and flattens them all to
a single body.

An advantage of this method is that you don't need to continously
teach list members to turn off HTML in their email client.
