I am constantly frustrated by correspondents with broken mailers who
send me attachments that are identified as application/octet-stream,
even though they have a specific type (90% of the time it's .doc;
another 9% is .pdf) that should be identified as such.
Since I can't do the right thing and fix the broken mailers, I did the
next best thing: I revised mm-display-part to pick out the proper type
based on the file extension. The revised version is below. The first
"when" clause is new; everthing else is the same. If people like the
idea, I'd like to see it get into the main tree (how do I make that
happen?).
(defun mm-display-part (handle &optional no-default)
"Display the MIME part represented by HANDLE.
Returns nil if the part is removed; inline if displayed inline;
external if displayed external."
(save-excursion
(mailcap-parse-mailcaps)
(if (mm-handle-displayed-p handle)
(mm-remove-part handle)
(let* ((type (mm-handle-media-type handle))
(method (mailcap-mime-info type)))
(when (and
(not method)
(equal type "application/octet-stream"))
(let* ((filename (cdr (assoc 'name (nth 1 handle))))
(start (string-match "\\.[^.]*$" filename)))
(when start
(setq type
(mailcap-extension-to-mime (substring filename start)))
(setq method (mailcap-mime-info type))
)))
(if (mm-inlined-p handle)
(progn
(forward-line 1)
(mm-display-inline handle)
'inline)
(when (or method
(not no-default))
(if (and (not method)
(equal "text" (car (split-string type))))
(progn
(forward-line 1)
(mm-insert-inline handle (mm-get-part handle))
'inline)
(mm-display-external
handle (or method 'mailcap-save-binary-file)))))))))

If at first you succeed, try to hide your astonishment.

In <http://thread.gmane.org/gmane.emacs.devel/46385>, Stefan Monnier
addressed the same or similar problems. But his patch (against the
stable branch = Gnus 5.11 in Emacs CVS) doesn't apply in the current
development sources and I didn't have time to resolve it manually yet.

A unified (or context) diff would be nicer.

Maybe you could investigate if Stefan's patch fits your needs?
I don't know if it works for your Gnus version (5.9), though.
Bye, Reiner.
