I have a Unix mailbox file that contains the following text in the body of a message: ---[ cut here ]--- EFCO also offers casements with integral blinds. See:=20 http://www.efcocorp.com/public/earm/products/default.asp?j=3D1&P=3D43&L=3D= 1=20 From that page, select select "Features and Benefits" from under the heading "Product Overview"=20 ---[ cut here ]--- mailbox.PortableUnixMailbox erroneously interprets the "From" at the beginning of the line as the beginning of a new message. Since 'From ' is only a valid header at the beginning of a message, perhaps the module could look at the following line and see if it looks like an RFC2822 header before accepting 'From ' as a message delimiter.

Logged In: YES user_id=1185570 Use rfc822.py in lieu of mailbox to first parse the message into an rfc822.Message... then pass it to the Mailbox.PortableUnixMailbox constructor.

Logged In: YES user_id=11375 See the comment in mailbox.py in the UnixMailbox class, too. UnixMailbox uses a stricter regex to look for from lines, but this proves too strict in practice so PortableUnixMailbox is much less strict. mbox format isn't very good, and we're just stuck with this behaviour. Closing this bug as "won't fix".
