How can I send email using Python?

Question

I am writing a program that sends an email using Python. What I have learned from various forums is the following piece of code:

#!/usr/bin/env python
impor         


        

Answer 1

If message headers, payload contain non-ascii characters then they should be encoded:

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from email.header    import Header
from email.mime.text import MIMEText
from getpass         import getpass
from smtplib         import SMTP_SSL


login, password = 'user@gmail.com', getpass('Gmail password:')
recipients = [login]

# create message
msg = MIMEText('message body…', 'plain', 'utf-8')
msg['Subject'] = Header('subject…', 'utf-8')
msg['From'] = login
msg['To'] = ", ".join(recipients)

# send it via gmail
s = SMTP_SSL('smtp.gmail.com', 465, timeout=10)
s.set_debuglevel(1)
try:
    s.login(login, password)
    s.sendmail(msg['From'], recipients, msg.as_string())
finally:
    s.quit()

According to the error message, you use the localhost as the SMTP server, then the connection was refused. Your localhost didn't have an SMTP sever running I guess, you need to make sure the SMTP server you connect is valid.

Answer 3

If you print the error message, you will likely get a comprehensive description of what error occurred. Try (no pun intended) this:

try:
    # ...
except Exception, error:
    print "Unable to send e-mail: '%s'." % str(error)

If, after reading the error message, you still do not understand your error, please update your question with the error message and we can help you some more.

Update after additional information:

the error message

socket.error: [Errno 111] Connection refused

means the remote end (e.g. the GMail SMTP server) is refusing the network connection. If you take a look at the smtplib.SMTP constructor, it seems you should change

server = smtplib.SMTP('smtp.gmail.com:587')

to the following.

server = smtplib.SMTP(host='smtp.gmail.com', port=587)
