bug#31145: 27.0.50; forwarding an html email in gnus mungs the headers if they contain a blank line

[Robert Marshall]

In gnus I C-c C-f'ed an email with multiple mimeparts one of which is
html.
That email also contains a blank line with the headers

------- header section
X-Spam-Report: Content analysis details: (2.2 points)
 
  pts rule name              description

------- end of extract but more lines of headers followed

When the user received the forward those headers read:

X-Spam-Report: Content analysis details: (2.2 points)
--=====-=-=
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="=====-=-="

 
  pts rule name              description

Looks like some part of the forwarding interpreted the blank line as the
end of the headers?
If necessary I can - off list - forward an email of both the original
and the corrupted forward.

Robert

Thanks.  I put it in an nndoc group and `C-c C-f'-d it
(with (setq message-forward-as-mime t) as that's what it looked like),
and I was unable to reproduce the bug.

The line in question wasn't completely empty -- it had a space in there,
and Message seemed to heed that as a continuation line, as it should.

I'll forward it to you so that you can see.  :-)

So I see! I've seen this bug on a variety of emails normally hits me
when I'm trying to forward spammy emails (inevitably with html
components) to our spam collector.

Thanks, I'll look at my other settings and see if I can produce a
-Q'able test case.

Were you able to reproduce the bug?

More information was requested, but no response was given within a few
months, so I'm closing this bug report.  If the problem still exists,
please reopen this bug report.
