[|'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):

The result should be 3 messages. If you forward any of the
messages, you'll see that the resulting message has the form:
|To:
|...
|
|
[Message part 4 (message/rfc822, inline)]
|>From level 1
|>>From level 2
|>>>From level 3
|...
|
[Message part 5 (text/plain, inline)]
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.
