Python - error (denial of relay access) when sending email

I got an error while trying to send an email using sendmail python. Here is my python code: (Pas dobjet)

#! /usr/bin/python

import smtplib

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

# me == my email address
# you == recipient email address
me = "my@email.com"
you = "email@gmail.com"

# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = me
msg['To'] = you

# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you?\nHere is the link you wanted:\nhttp://www.python.org"
html = """\
<html>
  <head></head>
  <body>
    <p>Hi!<br>
       How are you?<br>
       Here is the <a href="[http://www.python.org">link</a]http://www.python.org">link</a> you wanted.
    </p>
  </body>
</html>
"""

# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html')

# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)

# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
# sendmail function takes 3 arguments: sender address, recipient address
# and message to send - here it is sent as one string.
s.sendmail(me, you, msg.as_string())
s.quit()

When I send this email, I have this error:

Traceback (most recent call last):
  File "./mail.py", line 47, in <module>
    s.sendmail(me, you, msg.as_string())
  File "/usr/lib/python2.7/smtplib.py", line 747, in sendmail
    raise SMTPRecipientsRefused(senderrs)
smtplib.SMTPRecipientsRefused: {'email@gmail.com': (454, '4.7.1 <email@gmail.com>: Relay access denied')}

I really do not know why this does not work in production, since it works in a test environment. Can you please understand?

Additional information may be required. This error is probably caused by the domain configuration.

  • Is your email domain identical in TEST and PROD?
  • , PROD vs TEST, .
