	Most email from Yahoo is like this.  Yahoo doesn't know how
	to do quoted-printable properly.  It displays ok if you
	speak mime but not if you don't.  The intent of quoted-printable
	is to display ASCII nicely if you don't have a mime compliant
	reader.

	Mark

	RFC 2045.

   The Quoted-Printable encoding is intended to represent data that
   largely consists of octets that correspond to printable characters in
   the US-ASCII character set.  It encodes the data in such a way that
   the resulting octets are unlikely to be modified by mail transport.
   If the data being encoded are mostly US-ASCII text, the encoded form
   of the data remains largely recognizable by humans.  A body which is
   entirely US-ASCII may also be encoded in Quoted-Printable to ensure
   the integrity of the data should the message pass through a
   character-translating, and/or line-wrapping gateway.

	also

    (4)   (Line Breaks) A line break in a text body, represented
          as a CRLF sequence in the text canonical form, must be
          represented by a (RFC 822) line break, which is also a
          CRLF sequence, in the Quoted-Printable encoding.  Since
          the canonical representation of media types other than
          text do not generally include the representation of
          line breaks as CRLF sequences, no hard line breaks
          (i.e. line breaks that are intended to be meaningful
          and to be displayed to the user) can occur in the
          quoted-printable encoding of such types.  Sequences
          like "=0D", "=0A", "=0A=0D" and "=0D=0A" will routinely
          appear in non-text data represented in quoted-
          printable, of course.
