I have a message on my Exchange server that neither Netscape 4.73 or Mozilla can 
It's because of the attachment of the mail contains this text:

In both Mozilla and Netscape I'm only shown the header infomation and nuthing 
With Outlook Express everything works fine.

Just so I'm clear, when you view the example message you posted the message pane
(outside of the headers) is blank? that sounds bad. but 4x does the same thing....

Yes, the message pane is blank.

I routinely see this with 4.x and Mozilla. I just checked M18 and still see the 
problem there (Build ID 2000101014, NT 4.0 SP5). The workaround that has always 
worked for me is to forward the message to myself. I checked a couple of 
messages that show this problem and a couple that don't, and the "This body part 
will be downloaded on demand." string is present in the former but not the

I don't know about the "because" part. It may be related, but it's perfectly OK
to have attachments that aren't downloaded.

I suspect this has more to do with the multipart-mixed content type. Jeff, does
this make sense to you?

Not really. Is it possible to attach the mail source from Outlook Express?

John, Henrik, could you possibly attach the source of that mail from some mail
program that _is_ reading it completely?

Only for attachment file larger than 1MB.

I have recieved a number of e-mails displaying the same symptoms but from a
different message source.   I will attach the message source in question.

I see the same symptoms on mozilla 1.3a. Solaris build provided by Sun
Microsystems (downloaded from a mozilla mirror site). The message body shows
"This body part will be downloaded on demand."

No attachement pane is shown to download the (large) attachments from server. 

The message source shows complete message with inline attachement (html page in
this case).

Moving the message to local folders (not imap) shows the attachements. moving it
back brings the same problem back.

Email source

This email does not show the body nor the attachement pane as per above
(the mail addresses and server name/IP addresses have been changed)

I am seeing this in Mozilla 1.5rc2 and Thunderbird 0.3rc2. The IMAP server is
Microsoft Exchange 6 and copying the message to local folders (but not other
IMAP servers) fixes it.

The message body displays as "This body part will be downloaded on demand." And
the attachments ARE displayed correctly.

mail src that does this in thunderbird 0.3

This is the source of a message in my IMAP inbox that exhibits this problem
when viewed in Thunderbird 0.3. The source was obtained using View Source in
Thunderbird 0.3 itself, so the message is apparently fully downloaded, just not
correctly displayed.

Also seeing this problem under with a courier IMAP server and Mozilla 1.5. Seems
to happen to some multipart/mixed messages, but certainly not all of them. View
Source always works properly on them, and they will display properly when I go
into the INBOX properties, then offline, and select "Download all."

Do you have the menu item View | Display Attachments Inline checked or not? If
it's not checked, this bug is a dup and should already be fixed in the latest
nightly Thunderbird and Mozilla builds.

Comment 23

Not checked.

Still occuring in 1.6 Release, so I assume the bug fix for the bug this is a
dupe for didn't make it in to that branch. I'll pull down a Thunderbird build
and check with that.

Comment 24

yes, I don't think this made 1.6.

Comment 25

OK, Thunderbird 0.5a (20040120) does not exhibit the problem, even with the 
"Display Inline" turned off.

I still see this problem in Mozilla 1.7.8
UW IMAP server.

It happens very infrequently, but it seems like it is happening more for certain
users.  I could not yet verify that this is because it happens more for mail
from certain senders (it does not look like that).
