3.1.1 email problems

[foosion]

I've been having problems with email in 3.1.1. I decided to try the examples from the docs. Alas, the first I tried didn't work. I tried to send a directory whose only contents were a single zip file.

#!/usr/bin/env python

"""Send the contents of a directory as a MIME message."""

import os
import sys
import smtplib
# For guessing MIME type based on file name extension
import mimetypes

from optparse import OptionParser

from email import encoders
from email.message import Message
from email.mime.audio import MIMEAudio
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

COMMASPACE = ', '


def main():
    parser = OptionParser(usage="""\

SMTP server, which then does the normal delivery process.  Your local machine
must be running an SMTP server.
