Question

I am trying to send an email using python but despite I am using the local SMTP server it seems that it needs authentication. The code I run and the error I get can be seen below. I use port 587, because port 25 cannot be opened on my server. Could you please help me on setting up the local SMTP server using python on port 587?

>>> import smtplib
>>> from email.mime.text import MIMEText
>>> msg = MIMEText('Test body')
>>> me = '[e-mail]'
>>> to = '[e-mail]'
>>> msg['Subject'] = 'My Subject'
>>> msg['From'] = me
>>> msg['To'] = to
>>> s = smtplib.SMTP('localhost', 587)
>>> s.sendmail(me, [to], msg.as_string())

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/smtplib.py", line 722, in sendmail
    raise SMTPSenderRefused(code, resp, from_addr)
smtplib.SMTPSenderRefused: (530, '5.7.0 Authentication required', '[e-mail]')

Then before you attempt to use s.sendmail, you use s.login('user', 'password') – http://docs.python.org/2/library/smtplib.html#smtplib.SMTP.login

If you don’t have login details – then consult your system admin.
