Question

I have the following code

import smtplib
from email.mime.text import MIMEText



smtpserver = 'smtp.gmail.com'
AUTHREQUIRED = 1 # if you need to use SMTP AUTH set to 1
smtpuser = '[e-mail]'  # for SMTP AUTH, set SMTP username here
smtppass = '123456'  # for SMTP AUTH, set SMTP password here

RECIPIENTS = ['[e-mail]']
SENDER = '[e-mail]'

msg = MIMEText('dsdsdsdsds\n')
msg['Subject'] = 'The contents of iii'
msg['From'] = '[e-mail]'
msg['To'] = ''[e-mail]''

mailServer = smtplib.SMTP('smtp.gmail.com',587)
mailServer.ehlo()
mailServer.starttls()
mailServer.ehlo()
mailServer.login(smtpuser, smtppass)
mailServer.sendmail(smtpuser,RECIPIENTS,msg.as_string())
mailServer.close()

this code works fine on my desktop. but with this error failed
