See <http://docs.python.org/lib/module-email.Message.html> and
<http://docs.python.org/lib/module-mimetypes.html>

import mimetypes
for i in m.walk():
    if i.is_multipart():
        continue
    if i.get_content_maintype() == 'text':
        pl = i.get_payload(decode=True)
        ...
        continue
    att_name = i.get_filename(None)
    if not att_name:
        ext = mimetypes.guess_extension(i.get_content_type())
        att_name = 'makeitup%s' % ext
    pl = i.get_payload(decode=True)
    ...
