Python SMTP Error Code Handling

Question

I was looking for a fair cue ball and could not come up with anything satisfying.

I am trying to write a python program to listen for email failure reports and re-send them at various intervals depending on the reason for the rollback.

import smtplib
from smtplib import *

sender = '[e-mail]'
receivers = ['[e-mail]']

message = """From: From Arthur <[e-mail]>
To: To Deep Thought <[e-mail]>
Subject: SMTP e-mail test
This is a test e-mail message.
"""

try:
  smtpObj = smtplib.SMTP('smtp.gmail.com',587)
  smtpObj.starttls()
  smtpObj.login(sender,'[e-mail]')
  smtpObj.sendmail(sender, receivers, message)
  print "Successfully sent email"
except SMTPResponseException:
  error_code = SMTPResponseException.smtp_code
  error_message = SMTPResponseException.smtp_error
  print "Error code:"+error_code
  print "Message:"+error_message
  if (error_code==422):
    print "Recipient Mailbox Full"
  elif(error_code==431):
    print "Server out of space"
  elif(error_code==447):
    print "Timeout. Try reducing number of recipients"
  elif(error_code==510 or error_code==511):
    print "One of the addresses in your TO, CC or BBC line doesn't exist. Check again your recipients' accounts and correct any possible misspelling."
  elif(error_code==512):
    print "Check again all your recipients' addresses: there will likely be an error in a domain name (like [e-mail] instead of [e-mail])"
  elif(error_code==541 or error_code==554):
    print "Your message has been detected and labeled as spam. You must ask the recipient to whitelist you"
  elif(error_code==550):
    print "Though it can be returned also by the recipient firewall (or when the incoming server is down), the great majority of errors 550 simply tell that the recipient email address doesn't exist. You should contact the recipient otherwise and get the right address."
  elif(error_code==553):
    print "Check all the addresses in the TO, CC and BCC field. There should be an error or a misspelling somewhere."
  else:
    print error_code+": "+error_message

Why does the following error occur:

Traceback (last last call): File "C: / Users / Varun Shijo / PycharmProjects / EmailBounce / EmailBounceTest.py", line 20, in error_code = SMTPResponseException.smtp_code AttributeError: object type "SMTPResponseException" does not have the attribute "smtp_code"

- , SMTPResponseException ( smtplib ), , , (, MSG).

- ?

except SMTPResponseException as e:
    error_code = e.smtp_code
    error_message = e.smtp_error
