I am using the following code below:

import smtplib
import zipfile
import tempfile
from email import encoders
from email.message import Message
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart

#...

def send_file_zipped(the_file, recipients, sender='email@email.com'):
    myzip = open('file.zip', 'rb')


    # Create the message
    themsg = MIMEMultipart()
    themsg['Subject'] = 'File %s' % the_file
    themsg['To'] = ', '.join(recipients)
    themsg['From'] = sender
    themsg.preamble = 'I am not using a MIME-aware mail reader.\n'
    msg = MIMEBase('application', 'zip')
    msg.set_payload(myzip.read())
    encoders.encode_base64(msg)
    msg.add_header('Content-Disposition', 'attachment', filename=the_file + '.zip')
    themsg.attach(msg)
    themsg = themsg.as_string()

    # send the message
    smtp = smtplib.SMTP("smtp.gmail.com", "587")
    smtp.connect()
    smtp.sendmail(sender, recipients, themsg)
    smtp.close()

#running this
send_file_zipped('file.zip', 'email@email.edu')

I have tried different variations to try and make it connect successfully here, but I am at a loss here. The error I am getting is this:

Traceback (most recent call last):
File "/Users/Zeroe/Documents/python_hw/cgi-bin/zip_it.py", line 99, in <module>
send_file_zipped('file.zip', 'email@email.com')
File "/Users/Zeroe/Documents/python_hw/cgi-bin/zip_it.py", line 40, in send_file_zipped
smtp.connect()
File "/usr/local/lib/python3.2/smtplib.py", line 319, in connect
self.sock = self._get_socket(host, port, self.timeout)
File "/usr/local/lib/python3.2/smtplib.py", line 294, in _get_socket
return socket.create_connection((host, port), timeout)
File "/usr/local/lib/python3.2/socket.py", line 404, in create_connection
raise err
File "/usr/local/lib/python3.2/socket.py", line 395, in create_connection
sock.connect(sa)
socket.error: [Errno 61] Connection refused

I am going to assume that my issue lies in connecting with the smtp server, but I don’t know what I am missing. Any help would be greatly appreciated!!

    smtp.connect() is wrong/redundant. The smtplib.SMTP(...) calls .connect upon initialization. A bare .connect call without any parameters means connection to localhost and if you do not have a SMTP server running on your machine you’ll get an error.

    However your goal is to send mail through GMail. Note that GMail’s SMTP requires authentication, which you are not doing.

    Your last lines should be accordingly:

    # send the message
smtp = smtplib.SMTP("smtp.gmail.com",  587)
smtp.helo()
smtp.starttls()                 # Encrypted connection
smtp.ehlo()
smtp.login(username, password)  # Give your credentials
smtp.sendmail(sender, recipients, themsg)
smtp.quit()
