使用--smtp_host=smtp.gmail.com从dev服务器发送电子邮件

在问题的答案中 Error sending e-mail via SMTP server on App Engine development server 有一个 nice solution by Blixt :

"dev_appserver.py does not support TLS 
which is required by Gmail. You can 
enable it by adding a few lines in api/mail_stub.py:"

# After smtp.connect(self._smtp_host, self._smtp_port)
smtp.ehlo()
smtp.starttls()
smtp.ehlo()

但是Windows Vista不允许我更改 api/mail_stub.py

是否有其他方法从开发服务器发送邮件。其他选项(sendmail和isp不适合我)。谢谢!

编辑

我改变了 API/邮件存根.py 根据指示 here 我使用以下命令行选项:

dev_appserver.py  
--smtp_host=smtp.gmail.com 
--smtp_port=25 
--smtp_user=xxxx@gmail.com 
--smtp_password=gmail_pw 
C:\Users\A\Desktop\repeater # path to root directory

但我从日志控制台得到这个错误:

***********************************************************
2010-11-18 10:24:37 Running command: "['C:\\Python26\\pythonw.exe', 
'C:\\Program Files(x86)\\Google\\google_appengine\\dev_appserver.py',

'--port=8080', 
u'dev_appserver.py', 
u'--smtp_host=smtp.gmail.com', 
u'--smtp_port=25', 
u'--smtp_user=xxxx@gmail.com', 
u'--smtp_password=gmail_pw 
C:\\Users\\A\\Desktop\\repeater', 
'C:\\Users\\A\\Desktop\\repeater']"

Runs a development application server for an application.

dev_appserver.py [options] <application root>

Application root must be the path to the application to run in this server.
Must contain a valid app.yaml or app.yml file.

****************************************************

这是app.yaml:

application: re-peater
version: 1
runtime: python
api_version: 1

handlers:

- url: /favicon.ico
  static_files: static/images/favicon.ico
  upload: static/images/favicon.ico

- url: /stylesheets
  static_dir: stylesheets

- url: /.*
  script: repeater.py

所有这些都在没有这些命令行选项的情况下工作。有什么建议说明这不起作用吗?
