How to send an email with Gmail as provider using Python?

I am trying to send email (Gmail) using python, but I am getting following error.

Traceback (most recent call last):
File "emailSend.py", line 14, in <module>
server.login(username,password)
File "/usr/lib/python2.5/smtplib.py", line 554, in login
raise SMTPException("SMTP AUTH extension not supported by server.")
smtplib.SMTPException: SMTP AUTH extension not supported by server.


The Python script is the following.

import smtplib
fromaddr = 'user_me@gmail.com'
toaddrs = 'user_you@gmail.com'
msg = 'Why,Oh why!'
username = 'user_me@gmail.com'
password = 'pwd'
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

Answer

You need to say EHLO before just running straight into STARTTLS:

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

Also you should really create From:, To: and Subject: message headers, separated from the message body by a blank line and use CRLF as EOL markers.

E.g.

msg = "\r\n".join([
  "From: user_me@gmail.com",
  "To: user_you@gmail.com",
  "Subject: Just a message",
  "",
  "Why, oh why"
  ])
