[|'s added to quote From lines]

    If you forward a Rmail message containing a MIME message with "From "
lines, the mbox escaping of From lines is not properly done.


    Start emacs -q then evaluate the 9521 patch:

(require 'rmailmm)

(defun rmail-insert-mime-forwarded-message (forward-buffer)
  "Insert the message in FORWARD-BUFFER as a forwarded message.
This is the usual value of `rmail-insert-mime-forwarded-message-function'."
  (let ((message-buffer
	 (with-current-buffer forward-buffer
	   (if rmail-buffer-swapped
	       rmail-view-buffer
	     forward-buffer))))
    (save-restriction
      (narrow-to-region (point) (point))
      (message-forward-make-body-mime message-buffer))))


    Then run Rmail on the following mbox file (remove |'s at line start
first):

|Start with a Rmail message (this one will do) not containing MIME that
|contains lines like the following:

    The result should be 3 messages.  If you forward any of the
messages, you'll see that the resulting message has the form:

|To: 
|...
|
|

[-- Attachment #2: Type: message/rfc822, Size: 136 bytes --]


|>From level 1
|>>From level 2
|>>>From level 3
|...
|

[-- Attachment #3: Type: text/plain, Size: 194 bytes --]


Note that the From lines should be under mboxrd:

|From level 1
|>From level 2
|>>From level 3


    See #13328 for related discussion of properly decoding From lines in
MIME messages.
