Python的SMTP錯誤代碼處理

Question

我已經在這方面搜索了一點點，不能拿出任何滿意的東西。

我一直在試圖編寫一個python程序來偵聽電子郵件反彈報告，並根據反彈原因以不同的時間間隔重新發送它們。

import smtplib 
from smtplib import * 

sender = 'foo@bar.com' 
receivers = ['42@life.com'] 

message = """From: From Arthur <foo@bar.com> 
To: To Deep Thought <42@life.com> 
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,'foo@bar.com') 
    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 mail@domain.coom instead of mail@domain.com)" 
    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's 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 

對此我得到以下錯誤：

Traceback (most recent call last): File "C:/Users/Varun Shijo/PycharmProjects/EmailBounce/EmailBounceTest.py", line 20, in error_code = SMTPResponseException.smtp_code AttributeError: type object 'SMTPResponseException' has no attribute 'smtp_code'

我讀的地方，我應該嘗試從SMTPResponseException類（即使的smtplib文檔說otheriwse）的實例獲取屬性所以我也試過，但我不確定通過它的構造函數（代碼，味精）是什麼參數。

請問有人能推動我朝着正確的方向發展嗎？

謝謝。

嘗試

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