Incorrect inclusion of multiline headers

[Wojciech Komornicki]

Using: vm-8.1.1
Debug trace:
Debugger entered--Lisp error: (error "Invalid header line (maybe a continuation line lacks initial whitespace)")
  signal(error ("Invalid header line (maybe a continuation line lacks initial whitespace)"))
  error("Invalid header line (maybe a continuation line lacks initial whitespace)")
  mail-send()
  vm-mail-send()
  vm-mail-send-and-exit(nil)
  call-interactively(vm-mail-send-and-exit nil nil)
Reproduce: To reproduce you need a message from a mailer which does not format its headers correctly.

Some mailers include multiline headers without a space character indicate continuation of the header. For example
    References: <xxxxxxxxxxxxxxxx>
    <xxxxxxxxxxx>
The second line should be indented preferrably be a tab.
I suggest (I am not an expert on mail syntax) the following in vm-mail-mode-show-headers
   (save-excursion
    (goto-char (point-min))
    (while (not (looking-at "--text follows"))
      (forward-line 1)
      (if (looking-at "<")
 (insert-char 9 1))
I have modiffied the code in my implementation to fix the annoying message of invalid headers.

Hi,

The error you are getting is in mail-send, which is dealing with the message
you have composed. What does this have to do with other mailers?

In any case, I would need to have a sample message composition that produces
the problem.

Also, please let me know what happens if you run VM with all its default
settings.

Cheers,
Uday

Uday,
    Thanks for getting back to me and sorry for not being clear and not debugging my
    situation more thoroughly.

    The situation occurs when I reply to someone's mail message. Their "References:"
    headers are included but the continuation lines do not start with whitespace. When I
    do not include my .emacs file nor the system startup file I do not get the error
    mentioned below. I will slowly add various packages and see which is the offending
    package that causes the error.

    For know remove the bug report. Mea culpa.

Please check to see if you have changed vm-mail-mode-hidden-headers, in particular.

Cheers,
Uday

I think I have tracked down my bug and it is a bug I introduced in my .vm file. Since I
use supercite, the indentation provided by supercite does not work well with tabs. Hence
I have a hook which untabifies a buffer before it is passed to supercite. Unfortunately,
I did not realize that my hook also untabified the headers.

I hope that makes sense.

Ok, well done! I am closing the bug report now.
