[Spambayes] Email package and the CRLF pair

[Meyer, Tony]

I'm hoping that there are still some Python experts hanging about here
and they've just been quiet for a bit.

As you may have noticed, we ran into a bit of trouble recently with the
imap filter because messages had only \n (CR) and not \r\n (CRLF).
Message bodies don't really matter here; what matters are the headers.

As far as I can see*, when the email package** returns a message via
str() or as_string(), it only puts a CR after each header.  But RFC2822
says that:
  "Header fields are lines composed of a field name, followed by a colon
   (":"), followed by a field body, and terminated by CRLF." [Section
2.2]

Is this therefore a bug in the email package that I should report?
Advice from someone that knows more than me (is Barry there?) about
these things would be appreciated.

* Digging through the email Message module, then the Generator module,
then the Header module into the _encode_chunks function.
** Both in Python 2.2.2 and cvs.
