Some bug reports, perhaps?

Email has been "ported" in the sense that all the existing tests pass
under py3k.  It is not, however, fully functional:  it cannot handle
input that contains binary data with the high bit set.  (To put it another
way, the python3 email package currently handles only 7bit clean data.)
This has various unfortunate consequences for other standard library
packages (cgi, nntp, etc) that depend directly or indirectly on the
email package.

To fix this the email package API and a chunk of the internals needs
to be redesigned so that it can handle bytes while still providing a
string-based interface to the textual data.  This is no small task,
since email in python2 has been getting away with all kinds of dirty
tricks because of the lack of a clean bytes/string separation in python2.

See http://launchpad.net/python-email6 for current status of the project.

Prashant Kumar, if you would like to help with the email6 project, please
sign up to the email-sig mailing list and introduce yourself there.
All help is welcome!  It is not a "porting" project strictly
speaking, but it certainly is interesting :)
