为什么使用python发送Email时主题和内容为空？

Question

我尝试在远程服务器上运行以下 python 脚本（复制自 http://www.tutorialspoint.com/python/python_sending_email.htm）以发送电子邮件。我成功收到了邮箱里的Email，可惜内容总是空的。另一个问题是，如果我在“”“发件人：xxx”“”中稍微改变一下邮件，说删除这部分From: sender Name，那么我什至可以收到空电子邮件。消息行“”“xxx”“”中发生了什么神奇的事情？

import smtplib
def send_Email2():

    sender = 'username@company.com'
    receivers = "receivername@company.com"    
    message = """From: Sender Name  <username@company.com>
         To: Receiver Name <receivername@company.com>
         Subject: SMTP e-mail test

         This is a test e-mail message.
         """

   try:
       smtpObj = smtplib.SMTP('1xx.128.2.xxx',25)
       smtpObj.sendmail(sender, receivers, message)  
       print "Successfully sent email"
   except SMTPException:
       print "Error: unable to send email"

您是否尝试过以下方法：

message['Subject'] = 'SMTP e-mail test'
message['From'] = 'username@company.com'
message['To'] = 'receivername@company.com'
