smtplib.SMTPServerDisconnected：连接意外关闭

问题描述

我正在尝试使用django.core.mail send_mail在终端上执行以下代码

send_mail('some title','some text','[email protected]',['[email protected]'])

但执行后控制台显示此错误

Traceback (most recent call last):
  File "<console>",line 1,in <module>
  File "/home/adjtlikp/virtualenv/globalit-web/3.7/lib/python3.7/site-packages/django/core/mail/__init__.py",line 61,in send_mail
    return mail.send()
  File "/home/adjtlikp/virtualenv/globalit-web/3.7/lib/python3.7/site-packages/django/core/mail/message.py",line 284,in send
    return self.get_connection(fail_silently).send_messages([self])

  File "/opt/alt/python37/lib64/python3.7/smtplib.py",line 251,in __init__
    (code,msg) = self.connect(host,port)

    (code,msg) = self.getreply()
  File "/opt/alt/python37/lib64/python3.7/smtplib.py",line 394,in getreply
    raise SMTPServerdisconnected("Connection unexpectedly closed")
smtplib.SMTPServerdisconnected: Connection unexpectedly closed

我的settings.py

EMAIL_USE_TLS = True  
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'   
EMAIL_HOST = 'smtp.gmail.com'  
EMAIL_HOST_PASSWORD = 'mypass'  
EMAIL_HOST_USER = '[email protected]'   
EMAIL_PORT = 465 
DEFAULT_FROM_EMAIL = EMAIL_HOST_USER

我尝试更改EMAIL_PORT和EMAIL_HOST，但没有任何变化，有趣的是，在localhost中，代码可以正常工作，但是当我使用主机时，错误传给了我

解决方法

显示错误是因为我输入了错误的EMAIL_USE_TLS端口，原因是TLS，端口应该是25或587，原因是SSL，端口应该是465
