[plug] MIME Types by file contents

[Bernd Felsche]

I've almost finished the Python MIME mailer.

One problem I encountered was with the known MIME types having
dubious mappings to filename extensions. The code works around that
by using it's own "definitive" map of MIME type to extension.

The other problem that I've encountered and not yet resolved is with
the Python email module not liking news articles in particular.

I get a bunch of errors like:
bernie at pinion:~> python bin/maildoc.py bernie < z25 
Traceback (most recent call last):
  File "bin/maildoc.py", line 143, in ?
    if __name__ == '__main__': main()
  File "bin/maildoc.py", line 140, in main
    os.popen("/usr/sbin/sendmail -t","w").write(message.as_string())
  File "/var/tmp/python-2.2.2-build//usr/lib/python2.2/email/Message.py", line 107, in as_string

TypeError: 0

whenever I feed it a saved news item. It'll probably hiccup on email as well.

Other than that, it seems to handle any other input reliably; though
I've not done any cross-platform stuff yet.

See the attached bugfest for details.
