Many news postings do not display in thunderbird 0.9+ 20041126(and all previouus)
These appear to come from a variety of news posters, mostly outlook, the common
thread is a strangely constructed mime attachments, usually both some plain text
and html.  The issue may also related to relatively fancy "business card"
attachements. An example from an internal sgi newsgroup - the content is
relatively innocuous.

We have an immediate opportunity (decision to be made in the next week) to
supply 80TB of TP9500 storage which will be attached to an IBM AIX system
running GPFS. 

Do we have any experience of doing this elsewhere? Is there an account
manager you know I could talk to? Did we encounter any problems? I
understand that there are some firmware specific aspects such as failover
which could be problematic, or do we have work arounds?

Many thanks for your time, I'd be very grateful for any feedback you can
provide.

Reproducible: Always
Steps to Reproduce:
1. Recieve badly constructed news posting
2. Attempt to display
Note: view source can show the text


Actual Results:  
Blank message in the display window

Expected Results:  
displayed the posting
There is no boundary parameter in "Content-Type: multipart/alternative;" header.
How can a mailer detect bounday in this case?
Do you say should be displayed as "text/plain;" when "Content-Type: multipart"
header with no boundary parameter?

Since RFC 2045 says 'the "boundary" parameter is required for any subtype of the
"multipart" media type', '"Content-Type: multipart" header with no boundary
parameter' can be considered to be 'Invalid mail header".
If this is applied, this message can be considered to be "text/plain;" message
because default Content-Type is text/plain if no Content-Type header or invalid
or unknown mime type.
But in this case, "Content-Type" and "multipart/alternate" are valid.
And consider Jpeg file part or PDF part in such message and imagine Jpeg or PDF
data display as text.
I can not afford to it.
I think handling this message as "no part in multipart" is appropriate.

> I think handling this message as "no part in multipart" is appropriate.

The problem is that nothing at all is displayed for the message text.  
Displaying at least the plain text part would be better, trying to make sense of
the html better than that.

I realize this is an incorrectly formed posting - but it's what many news
posters,  notably several versions of outlook, produce.  It may not be right,
but it is common, at least in the postings I see largely inside my company which
is mostly an outlook shop.  Thunderbird should be more forgiving - other mail
readers (e.g. outlook) are.  I think this is one of those "accept everything,
and send only the most correct" cases.    The problem may also be in the
mail-news gateway we use at SGI - I'm still trying to sort that out.

How the part(text or html) can be found when no boundary parameter?
Do you say search line start with "--"?
Do you say search "Content-Type" lines in body data portion in addition to
header portion of message?
Please note that body data before first boundary *SHOULD* be ignored.

Good question - maybe NextPart to NextPart for starters - that seems to give at
least the text, then the next one the html - whatever is doing this appears to
be using NextPart to mark the various sections.

I find it hard to believe that this structure is "common."  Do you have any idea 
what news client generated the message?  (It does not appear to be Outlook.)
The bug really needs to be filed against that program, not Mozilla.

That said, there are other bugs asking for support for other sorts of malformed 
messages, so why not this one too?

On further investigation, the damage appears to be caused by an news-mail
gateway script.  We're looking at fixing it, provided we can find someone who
actually can understand this particularly ancient piece of code.

But - outlookexpress (and presumably outlook) displays these messages through
it's newsreader, although with the notation:

This message is in MIME format. Since your mail reader does not understand
this format, some or all of this message may not be legible.

------_=_NextPart_000_01C50EBC.6EEDF53A
Content-Type: multipart/alternative;
boundary="----_=_NextPart_001_01C50EBC.6EEDF53A"


------_=_NextPart_001_01C50EBC.6EEDF53A
Content-Type: text/plain

i.e. it shows the bad stuff verbatim.

It would seem that thunderbird should be at least as tolerant.
This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
