The module that speaks the wire protocol should do the
conversion.  IMO, there's no other way to guarantee that
you're RFC compliant.  You could be getting your data from
the email package, but you could be getting it from anywhere
else, and /that/ source may not be RFC line ended either. 
Since you can't change every possible source of data for
NNTP or SMTP, your network interface must guarantee conformance.

Ok, thanks.
But what if I don't use the smtplib module?

I discovered the bug because I have written a small NNTP
server with twisted, using email module for parsing...

Correct; this is by design.  If you're worried about
protocols such as RFC 2821 requiring \r\n line endings,
don't. The smtplib module automatically ensures proper line
endings for the on-the-wire communication.
