我正在尝试在本地计算机上模拟 stmp 网络流量。我将 smtp 和 asyncore 模块用于服务器脚本，将 smtplib 和电子邮件模块用于客户端脚本。我的大部分代码都是从https://pymotw.com/2/smtpd/复制的。但是，我收到一个错误，指出 asyncore.py 读取正在引发 NotImplementedError 异常

这是我用于 emailServer.py 的代码：

#!/usr/bin/python
import smtpd
import asyncore

class CustomSMTPServer(smtpd.SMTPServer):

    def process_Message(self, peer, mailfrom, rcpttos, data):
        print 'Receiving message from:', peer
        print 'Message addressed from:', mailfrom
        print 'Message addressed to:  ', rcpttos
        print 'Message length        :', len(data)
        return

server = CustomSMTPServer(('127.0.0.1', 1025), None)

asyncore.loop()

emailClient.py 的代码：

#!/usr/bin/python

import smtplib
from email.mime.text import MIMEText
import email.utils

msg = MIMEText('This is the body of the message')
msg['To'] = email.utils.formataddr(('Recipient',    'recipient@example.com'))
msg['From'] = email.utils.formataddr(('Author', 'author@example.com'))
msg['Subject'] = 'Simple test message'

server = smtplib.SMTP('127.0.0.1', 1025)

server.set_debuglevel(True)

try:  
    server.sendmail('author@example.com' , ['recipient@example.com'],    msg.as_string())

except Exception as err:
    print(err)

finally:
   server.quit()

我在服务器端收到的错误：

error: uncaptured python exception, closing channel <smtpd.SMTPChannel    connected 127.0.0.1:51374 at 0x10bf0bb00> 
(<type 'exceptions.NotImplementedError'>: [/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/asyncore.py|read|83]

客户端的调试和错误语句：

    raise SMTPServerDisconnected('please run connect() first')
smtplib.SMTPServerDisconnected: please run connect() first

我相信相关的错误语句是来自客户端错误输出的 'exceptions.NotImplementedError'>: [/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/asyncore.py|read|83] 。SMTPServer 类的文档说 SMTPServer 自动绑定到 asyncore。如何解决此错误？

用户VPfB在评论中提供了解决方案。我的函数有错字。process_Message 应该是 process_message
