User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030624 When forwarding an email as an attachment with all headers the headers in the attached email are displayed incorrectrly. To be precise: Looking at the Sent folder copy: - the headers of the email forwarded by the sent email show only a subset of the email headers actually sent. This can be confirmed by checking the contents of the actual mail folder file. - the headers that are displayed for the mail forwarded by the sent email contain values from the original, forwarded email as well as from the forwarding email. Again, inspection of the displayed message headers and the actual mail folder file will confirm this. Looking at the received email: - the headers of the email forwarded in the received email show only a subset of the email headers actually received. This can be confirmed by checking the contents of the actual mail folder file. - the headers that are displayed for the mail forwarded by the received email contain values from the original, forwarded email as well as from the forwarding email. Again, inspection of the displayed message headers and the actual mail folder file will confirm this. Reproducible: Always Steps to Reproduce: 1. Select and view an email from the Inbox. 2. Make sure all headers are displayed. 3. Forward the email as an attachment to yourself. 4. Wait until the forwarded is received. 5. Compare email headers in Sent folder, an in the original and forwarded emails in the Inbox. The headers of the forwarding (container) email and the forwarded (contained) email should also be compared, and the displayed data should be cross checked with the data in the folder files. I will upload header file data from real emails forwarded. File Index: 1 - Headers from original message received (from file - matches displayed header in content, if not in order) 2a - Headers from forwarding email sent (from file - matches displayed header in content, if not in order) 2b - Headers from message attached by the forwarding email in Sent folder (from file) 2c - Headers from message attached by the forwarding email in Sent folder (from displayed message) 3a - Headers from forwarding email received (from file - matches displayed header in content, if not in order) 3b - Headers from message attached by the forwarding email received (from displayed message) 3c - Headers from message attached by the forwarding email received (from file, not from displayed message) Actual Results: This is a corruption of the data on display. The data displayed is not consistent with the data in the mail folder file. Header names and content displayed not consistent with the data actually sent or received. The headers displayed are a subset of the values contained in the actual mail file and the header values are intermingled with header values from the containing email. This makes it near impossible to deal with the "abuse" groups of various ISPs. Depending on whether they also use Mozilla, the header data provide to them is useless or points back to myself. Other users complain about headers for forwarded email not being a complete list or wrong or a combination thereof. Reports vary with the level of attention users pay to the actual header name and values. Expected Results: The headers (names and values) displayed should be identical to the headers contained within the mail file.
