This little function will give you the command used by mailcap for a
given file:

(defun get-mailcap-for-file (filename)
  "Get the command to use for FILENAME from mailcap file.
The command is like <command %s> and is meant to use with `format'."
  (let* ((ext  (file-name-extension filename))
         (mime (when ext (mailcap-extension-to-mime ext))))
    (when mime (mailcap-mime-info mime))))

(get-mailcap-for-file "foo.pdf")
==> "xpdf %s"
