Python Error: 5.7.0 must issue a starttls command first

Question

I try to send an email with my python script, but I got the error message:

5.7.0 must issue a starttls command first

I'm using smtplib and this is my code:

import smtplib

sender = 'from@fromdomain.com'
receivers = 'to@todomain.com'

message = """From: From Person <from@fromdomain.com>
To: To Person <to@todomain.com>
Subject: SMTP e-mail test

This is a test e-mail message.
"""

try:
    smtpObj = smtplib.SMTP('smtp.gmail.com')
    smtpObj.sendmail(sender, receivers, message)         
    print "Successfully sent email"
except Exception,e:
    print str(e)

If some one have an idea about how to solve this error I'll be grateful.

Answer 1

GMail won't let random users send mail through their SMTP servers.

As the error says, you'll have to call SMTP.starttls first and authenticate.
