最近部署了GSIL github敏感信息掃描 工具，掃描后無法發(fā)送郵件。
GSIL項目地址：https://github.com/FeeiCN/GSIL
提示的錯誤信息如下：

Traceback (most recent call last):
  File "/usr/lib/python3.6/smtplib.py", line 387, in getreply
    line = self.file.readline(_MAXLINE + 1)
  File "/usr/lib/python3.6/socket.py", line 586, in readinto
    return self._sock.recv_into(b)
ConnectionResetError: [Errno 104] Connection reset by peer

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/root/GSIL/gsil/notification.py", line 67, in notification
    s.ehlo()
  File "/usr/lib/python3.6/smtplib.py", line 441, in ehlo
    (code, msg) = self.getreply()
  File "/usr/lib/python3.6/smtplib.py", line 391, in getreply
    + str(e))
smtplib.SMTPServerDisconnected: Connection unexpectedly closed: [Errno 104] Connection reset by peer

請問各位大佬遇見過這種問題嗎？google了也沒找到相關(guān)的解決辦法，請各位大佬指教。謝謝。
