   Would you please fix this bug in metamail.el in the latest Emacs?
   (Are you still maintaining it?)

This is because rmail-ignored-headers includes MIME related headers,
such as "Content-Type:".  Simple user level solution is to put the
following code in .emacs.  It is much better to remove these headers
from rmail-ignored-headers in the next release of emacs distribution.

;; Leave MIME related headers.
(let ((headers '("\\|^mime-version:"
                 "\\|^content-transfer-encoding:"
                 "\\|^content-type:"))
      (case-fold-search t))
  (while headers
    (if (string-match (regexp-quote (car headers)) rmail-ignored-headers)
        (setq rmail-ignored-headers
              (concat (substring rmail-ignored-headers 0 (match-beginning 0))
                      (substring rmail-ignored-headers (match-end 0)))))
    (setq headers (cdr headers))))
