mailbox._Subfile's readline() will chop off the first character of the next line when reading Unix-style terminated files. It's surprising no one has mentioned this before. The problem lies in line mailbox._Subfile.readline() itself where self.pos is assigned self.fp.tell()'s value. You will need to subtract 1 from self.pos if a file uses unix-style termination.

Logged In: YES user_id=286435 There doesn't seem to be a clean way to fix the code. But there is a rather satisfactory workaround: Open the mbox file in binary mode for Unix (and Mac?) style terminated files. This should DEFINITELY be mentioned in the mailbox module docs.

I guess this bug report is out of date: mailbox.py doesn't seem to contain a _Subfile class, the ProxyFile.readline() function is one line, and there's no self.pos variable either. Probably 2.5's rewrite of the module removed this code.
