Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
[Message part 1 (text/plain, inline)]
[|'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):

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

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
I don't use rmail much myself, but I vaguely recall that there was a
similar bug report about this, and that this had been fixed at some
point.
Perhaps Eli remembers; added to the CCs.

I don't remember, sorry. I also didn't see anything pertinent in the
Git logs.
Moreover, upon re-reading the original report several times, I don't
think I understand what exactly is the bug: the original report is a
multipart message which is hard to parse. It also shows what I think
is a single message, but says "The result should be 3 messages", which
left me utterly confused.
I'd prefer to have a description with 2 attachments: the original
message, and the forwarded message. And the description should tell
in full what was expected to be seen, and why, preferably without
using ellipsis and hard-to-understand terminology such as "under
mboxrd".
Is it possible to get such a detailed report? Then I could try the
messages here and see if there's still a problem left in our current
sources.
At this point I can only say that I'm forwarding email with MIME
attachments quite a lot, and didn't spot any problems, although I
admit there's not a lot of ">>...>From" in them.

Here's a message with a From line:
From thing lala yes
If you can forward this as MIME in rmail, then I think the bug has been
fixed?

Then I guess this problem no longer exists, and we can close this bug;

This bug concerns trying to forward an existing message in a Rmail
mbox. Thus, the easiest way is to start with a known Rmail file. I've
attached a gziped mbox file; save it and gunzip it.
Now, start emacs 28.1 -q, find the mbox file, then do M-x
rmail-mode. You should have three messages. Try forwarding any of them
with 'f'; you will see that there are extra >'s in the proposed message
to send; this is the bug. (There should be no >s before From level 1, 1
'>' before From level 2, etc.) It is no longer necessary to worry about
the patch for 9521.
Pictorially, the text we are trying to forward should be:
|From level 1
|>From level 2
|>>From level 3
where the leading |s are to prevent quoting.
Note that this bug is likely related to #13328
(https://debbugs.gnu.org/cgi/bugreport.cgi?bug=13328).

If you look closely, you can actually see the bug in the your
previous test -- a '>' got added in front of the From in the message you
test forwarded ('>From thing lala yes').

I just did, and I don't see the bug (in Emacs 28.2). The mbox file I
get does include a line that begins with ">From", but in the message
buffer presented by Rmail to me I see just "From", with the ">"
removed.
I see the same in Emacs 28.1, so I'm unsure why you see the problem
there. Maybe the reproduction recipe above is too simple, and
something else is missing to reproduce the problem?

And now I've also sent to myself a message with a MIME attachment,
where the attachment was a text that included a line that began with a
"From". In the message I received, if I tell Rmail to show the
attachment, I see that line without any leading ">" before "From". So
again, I'm unable to reproduce the problem you are describing.
Are you sure you are using rmail.el which came with Emacs 28?

Hmm. What mailer did you used to send the message? Maybe it wasn't
sending a MIME message? We know that #13328 doesn't show the extra >
for non-MIME messages.
I was using Emacs Rmail, but not the pure emacs 28.1 -q because I
need to change settings to send email. Let me see if I can try a purer
reenactment.
Can you check the mbox I sent to see if you see extra >s for the
last 2 messages there? Can you send me the pieces of your mbox with the
2 test messages you sent (use binary attachment to avoid corruption)?
Clearly, one of our two set ups is different. :-(

How did your mailer encode the attachment? If it used base64, then
I don't expect you'll see the bug.

For the test with the existing mbox, yes. I downloaded and built
from source Emacs 28.1 and invoked it with -q, which should mean it
looks at none of my elisp.

Ok, I sent myself a message with last line "From nothing" (pure text
body); fetchmail produced the attached incoming_sample.gz file, which
Rmail 'g' added to an empty Rmail file to produce the attached
RMAIL.sample.gz. I did this using as pure an Rmail set up as I can with
emacs 28.1. My sending/receiving goes through MIT email forwarding and
uses Gmail as a receiving service.
Both of these files have the proper mbox quoting, with a > before the
From in the body. If I switch to emacs 28.1 -q and open that Rmail
file, I see the extra > and pressing 'f' includes it in the forwarded
message. This shows both bugs (13328 and 13329).
See if you can open RMAIL.sample and reproduce the bugs on your end.
If so, something must differ between our email sending/receiving before
rmail processes. If you can't reproduce the bugs given the Rmail file,
I'm very confused.

Rmail, with sendmail-user-agent as the sending MUA.

That wasn't clear originally, but later I sent "From" in an
attachment, and didn't see any ">From" in the received email. I also
don't think there's a need to do anything with "From" in an
attachment, since attachments are encoded.

I see >From and >>From etc. in the attachments, but I don't understand
how the > part appeared there in the first place: attachments cannot
be possibly taken for the beginning of another email.

It was base64, but that's the default used by Rmail, because I didn''t
change anything, just used the mail-add-attachment command, and the
file I attached was plain-ASCII file.

Then I have no idea what is going on, but from my testing the problem
doesn't exist. Perhaps your configuration of email happens to trigger
some rare situation, but I'd need a clear recipe starting from "emacs -Q"
to reproduce it. Or maybe your MTA has something to do with that?

So, to summarize:
. the problem happens only in emails that have MIME-Version: header
. the problem happens only in emails that have just the body, no
attachments
. the problem happens because rmail-show-mime doesn't remove the ">"
from ">From" when it shows the plan-text MIME content
Is that correct?

It seems like we need more information here in order to make any
progress. Mark, could you answer the questions above?
