outlook邮箱SMTPDataError 550传递结果横幅

Question

我在我的web应用程序中使用outlook邮箱的smtp服务。在过去的几天里，它运行得很好。然而，在通常的测试过程中发生了突然的错误：

File "/usr/lib/python3.4/smtplib.py", line 799, in sendmail
   raise SMTPDataError(code, resp)
smtplib.SMTPDataError: (550, b'5.3.4 554-554 5.2.0 STOREDRV.Deliver;delivery result banner')

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/usr/lib/python3.4/threading.py", line 920, in _bootstrap_inner
  self.run()
File "/usr/lib/python3.4/threading.py", line 868, in run
  self._target(*self._args, **self._kwargs)
File "/home/lancecopper/code/python/flasky/app/email.py", line 9, in send_async_email
  mail.send(msg)
File "/home/lancecopper/code/flasky/venv/lib/python3.4/site-packages/flask_mail.py", line 492, in send
  message.send(connection)
File "/home/lancecopper/code/flasky/venv/lib/python3.4/site-packages/flask_mail.py", line 152, in __exit__
  self.host.quit()
File "/usr/lib/python3.4/smtplib.py", line 867, in quit
  res = self.docmd("quit")
File "/usr/lib/python3.4/smtplib.py", line 403, in docmd
  self.putcmd(cmd, args)
File "/usr/lib/python3.4/smtplib.py", line 349, in putcmd
  self.send(str)
File "/usr/lib/python3.4/smtplib.py", line 341, in send
  raise SMTPServerDisconnected('please run connect() first')
smtplib.SMTPServerDisconnected: please run connect() first

我对smtp的底层机制知之甚少。有谁能给我一些关于这种错误的线索。

顺便说一下，我是一个住在GFW (中国防火墙).Would中的穷人，上面的错误有可能是GFW中断造成的吗？

我在使用mutt时遇到了这个问题。
