Error sending email: raise SMTPAuthenticationError(code, resp)

问题

Im trying to send emails with smtp module, but Im having an error:

File "/usr/lib/python2.7/smtplib.py", in login    
 raise SMTPAuthenticationError(code, resp) smtplib.SMTPAuthenticationError: (534, '5.7.14)...

Someone already had this error? Do you know how to fix?

The code:

def sendNotification():
    recepients_list = "emailsmtplibtest@gmail.com"
    subject = 'Subject'
    message = "Message" 
    sendemail(recepients_list,subject,message)

def sendemail(to_addr_list, subject, message):
    username = 'emailsmtplibtest@gmail.com'
    password = 'passtest'   
    from_addr = 'emailsmtplibtest@gmail.com'    
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.ehlo()
    server.starttls()
    server.login(username,password)
    newmessage = '\r\n'.join([
              'To: %s' %recepient_list,
               'From: %s' % from_addr,
                'Subject: %s' %subject,
                '',
                message
                ])
    try:    
        server.sendemail(from_addr, to_addr_list,newmessage)
        print 'notification sent'
    except:
        print 'error sending notification'
    server.quit()


sendNotification()

Go to Google's Account Security Settings: www.google.com/settings/security

Find the field "Access for less secure apps". Set it to "Allowed".

Try your script again, changing server.sendemail() to server.sendmail()

(534, b'5.7.14 Please log in via your web browser and\n5.7.14 then try again.\n5.7.14 Learn more at\n5.7.14 https://support.google.com/mail/answer/78754 h16sm7090987wrc.89 - gsmtp')

Allow less secure apps: ON Some apps and devices use less secure sign-in technology, which could leave your account vulnerable. You can turn off access for these apps (which we recommend) or choose to use them despite the risks.

I had exactly the same problem. Yes, it worked. By enabling your gmail account security setting -> Allow less secure app, I was able to send a simple email from one gmail to another gmail account.

WARNING: Allowing low security for apps accessing your Google account is not recommended by google. It can be a security threat. Turn it OFF after the experiment.
