305822 - Using email files where a message line starts with "From " results in an extra message

Status: RESOLVED INVALID

(Thunderbird :: Migration, defect)

Description

[Keith Price]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla Thunderbird Version 1.0.6 (20050716)

Given an email file, e.g. from Unix, when I copy that file to the appropriate
folder for Thunderbird and read it, an extra message is generated when a line in
the message body starts with "From ". All the other messages are handled properly.
This is not an issue with new messages since it seems to be explicitely handled
(i.e. the "From " is replaced with ">From " when reading the message).

Reproducible: Always

Steps to Reproduce:
1. Send a message to a Unix account -- Contents don't matter, except that
somewhere a line should start with "From " (without the Quotes).
2. Save the mail on Unix to a file (e.g. using Pine)
3. Copy the file to the mail folder on the PC
4. Run Thunderbird and look at the mail

Actual Results:  
The message is broken into 2 messages at the From.

Expected Results:  
There should be only 1 message.

It may be easier to just "fix" all my mail archive files to not have the From in
the body of the message -- once I fix them I won't notice whether the problem is
there anymore.

that's the way our mailbox format (berkeley mailbox format) works - an unescaped
from line indicates the start of a new message. Marking invalid - we don't
support copying a unix mail file that's not in berkeley mailbox format directly
into a tbird user profile...
