User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910

I received a mail message which ended up with:

"F-35042 RENNES (FRANCE)[removed]"

The message was sent only once, but I had too copies in my inbox. The messages
were the exact same (some <Ctrl-U> source), except that in one of the copies,
the above line had been replaced with:

"F-35042 RENNES (FRANCX-Mozilla-Status:[removed]"

Since Outlook express shows the same content for that message, I suspect Mozilla
has somehow corrupted/rewritten the content of the message. Sounds like a
dangling pointer somewhere.

FYI, I use an IMAP account with a Sun One mail server.

Reproducible: Didn't try

Steps to Reproduce:
Don't know how to reproduce, sorry.

Expected Results:  
Mozilla should not have modified the content of the message. This was relatively
harmless here, but points out a potential severe problem.

Hmm, I'm not sure what we can do with this bug... if we don't have steps to
reporduce its really hard to do any testing.  Could you attach the original mail
maybe and we can see if we can get it to reproduce?

It regularly happens to me that my Inbox shows the exact same message twice. I
think this generally happens when I have been reading/deleting messages from the
standalone mail message window. When I come back to the main (three-pane)
window, my Inbox sometimes shows two entries for the exact same message. I
haven't checked if the content was different for both entries. I generally
switch to a different folder, and then come back to Inbox, and there is only one
entry left for the "faulty" message. I always fear my mailbox may be corrupted
as a result. I too use an IMAP server.

Okay, this is becoming closer to something that I can test...  Just a couple
more things I need to know.  1) What do you mean by the stand alone mail message
window.  Are you talking about Thunderbird or double click on a mail-message and
then use that button to delete?  I'm going to attemtp testing assuming the
latter.  2) How often/or how long does it take for this to happen?  Does this
take 15 minutes, 10 e-mails or is it just random.  I'll see if I can reproduce
this based on how I understand things...  Also, please note what your system and
build are so we can be certain we are attempting to reproduce with the same
system.  Thanks.

Okay, I launched message pane by double clicking on a message and deleted about
15 message - at one point 10 in a row - and I was not able to reproduce this bug
on my machine.  Please see if you can provide us with a test case in which you
can reproducibly get this to happen and I'll be happy to test that as well.

I'm currently using Mozilla 1.6b. This has happenned since at least Mozilla 1.4.
It does take quite a number of emails for this to happen. Yes, by the standalone
email window, I mean the separate window you get when you double-click on a
specific message. I do all my email reading through that window. I'm on WinXP

I did not find any other related bug, so I post this here:

Mozilla also modifies my mail if it finds the "from" keyword somewhere in the
body of an e-mail, e.g.

from now on the "old" customer systems in the DEMO System Group
X-Mozilla-Status: 8000
X-Mozilla-Status2: 00000000
are no longer started by default.

Here the two added lines starting X-Mozilla-Status... are unexpected. It seems
as if the "from" is parsed as the header starting "From"

I get my mail using fetchmail. Any "From" in the beginning of a line is replaced
by " From", but not the "from". Is the case important here?

Two questions:

1. Has this been fixed already?

2. If not, which further information do you need?

Cheers, Jörg

Mail received from mailing list and changed by mozilla

I just found an e-mail from a sourceforge mailing list, so you may compare the
original on and my version as saved by mozilla.

In this mail, Mozilla changes my mail in the quoted part of the message.

> Quick Fix Developers,
> =A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0 I am sending a MassQuote message =
from an Initiator to an =20
X-Mozilla-Status: 8000
X-Mozilla-Status2: 00000000
> Acceptor using QuickFIX 1.9.4, the message is rejected by the acceptor =
> with error:

It seems like the "from" at the start of the line triggered this.

This mail is on

Attached is the version as I received it from the mailing list (using fetchmail
from an IMAP server and then Mozilla movemail)

Cheers, Jörg
