[Tutor] How do I get my machine to run an SMTP server?

[Grady Henry]

This is a program that I wrote using the third example at 12.2.13 Examples at python.org.

#!/usr/bin/env python

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

Usage: dirmail [options] from to [to ...]*

Options:
    -h / --help
        Print this message and exit.

    -d directory
    --directory=directory
        Mail the contents of the specified directory, otherwise use the
        current directory.  Only the regular files in the directory are sent,
        and we don't recurse to subdirectories.

`from' is the email address of the sender of the message.

`to' is the email address of the recipient of the message, and multiple
recipients may be given.

The email is sent by forwarding to your local SMTP server, which then does the
normal delivery process.  Your local machine must be running an SMTP server.

def usage(code, msg=''):
    print >> sys.stderr, __doc__
    if msg:
        print >> sys.stderr, msg
    sys.exit(code)


def main():
    try:
        opts, args = getopt.getopt(sys.argv[1:], 'C:', ['help', 'directory='])
    except getopt.error, msg:
        usage(1, msg)

    dir = os.curdir
    for opt, arg in opts:
        if opt in ('-h', '--help'):
            usage(0)

        usage(1)

    sender = args[0]
    recips = args[1:]

    # Create the enclosing (outer) message
    outer = MIMEMultipart()
    outer['Subject'] = 'Contents of directory %s' % os.path.abspath('C:\Documents and Settings\User\\My Documents')
    outer['To'] = COMMASPACE.join('gwhjr at bigfoot.com')
    outer['From'] = 'gwhjr at cox.net'
    outer.preamble = 'You will not see this in a MIME-aware mail reader.\n'
    # To guarantee the message ends with a newline
    outer.epilogue = ''

    for filename in os.listdir('C:\Documents and Settings\User'):
        path = os.path.join('C:\Documents and Settings\User', 'My Documents')
        if not os.path.isfile('C:\Documents and Settings\User'):
            continue
        # Guess the content type based on the file's extension.  Encoding
        # will be ignored, although we should check for simple things like
        # gzip'd or compressed files.
        ctype, encoding = mimetypes.guess_type('C:\Documents and Settings\User\\My Documents')
        if ctype is None or encoding is not None:
            # No guess could be made, or the file is encoded (compressed), so
            # use a generic bag-of-bits type.
            ctype = 'application/octet-stream'
        maintype, subtype = ctype.split('/', 1)
        if maintype == 'text':
            fp = open('C:\Documents and Settings\User\\My Documents')
            # Note: we should handle calculating the charset
            msg = MIMEText(fp.read(), _subtype=subtype)
            fp.close()
        elif maintype == 'image':
            fp = open('C:\Documents and Settings\User\\My Documents', 'rb')
            msg = MIMEImage(fp.read(), _subtype=subtype)
            fp.close()
        elif maintype == 'audio':
            fp = open('C:\Documents and Settings\User\\My Documents', 'rb')
            msg = MIMEAudio(fp.read(), _subtype=subtype)
            fp.close()
        else:
            fp = open('C:\Documents and Settings\User\\My Documents', 'rb')
            msg = MIMEBase(maintype, subtype)
            msg.set_payload(fp.read())
            fp.close()
            # Encode the payload using Base64
            Encoders.encode_base64(msg)
        # Set the filename parameter
        msg.add_header('Content-Disposition', 'attachment', filename=filename)
        outer.attach(msg)

    # Now send the message
    s = smtplib.SMTP()
    s.connect()
    __init__(self, host='', port=25, local_hostname=None)
    s.sendmail('gwhjr at cox.net', 'gwhjr at bigfoot.com', outer.as_string())
    s.close()


if __name__ == '__main__':
    main()

When I run the program using IDLE, I get the following:

Send the contents of a directory as a MIME message.

Usage: dirmail [options] from to [to ...]*

Options:
    -h / --help
        Print this message and exit.

    -d directory
    --directory=directory
        Mail the contents of the specified directory, otherwise use the
        current directory.  Only the regular files in the directory are sent,
        and we don't recurse to subdirectories.

`from' is the email address of the sender of the message.

`to' is the email address of the recipient of the message, and multiple
recipients may be given.

The email is sent by forwarding to your local SMTP server, which then does the
normal delivery process.  Your local machine must be running an SMTP server.

Traceback (most recent call last):
  File "C:\Documents and Settings\User\Desktop\EB2.py", line 125, in ?
    main()
  File "C:\Documents and Settings\User\Desktop\EB2.py", line 65, in main
    usage(1)
  File "C:\Documents and Settings\User\Desktop\EB2.py", line 48, in usage
    sys.exit(code)
SystemExit: 1

I guess that my first question is how do I get my machine to run an SMTP server?

Also, I'd like to say that I greatly appreciate all of the help that I've gotten in the past.
