title: How to send an email without login to server in Python
body: <p>I want to send an email without login to server in Python. I am using Python 3.6.
  I tried some code but received an error. Here is my Code :</p>
  
  <pre><code>import smtplib                          
  
  smtpServer='smtp.yourdomain.com'      
  fromAddr='from@Address.com'         
  toAddr='to@Address.com'     
  text= "This is a test of sending email from within Python."
  server = smtplib.SMTP(smtpServer)
  server.set_debuglevel(1)         
  server.sendmail(fromAddr, toAddr, text) 
  server.quit()
  </code></pre>
  
  <p>I expect the mail should be sent without asking user id and password but getting an error :</p>
  
  <blockquote>
    <p>"smtplib.SMTPSenderRefused: (530, b'5.7.1 Client was not authenticated', 'from@Address.com')"</p>
