Question

这是我的代码，我不知道为什么服务器一直意外关闭。我知道登录凭据绝对正确，但是如果输入错误，它将无法正确连接到getgo？那为什么会意外关闭呢？我感觉我没有使用正确的端口？我也尝试过使用server.startTLS（），但仍然不起作用：

#Send Email
server = smtplib.SMTP('smtp.gmail.com', 465)
server.connect('smtp.gmail.com', 465)
server.ehlo()
server.login("username@gmail.com","password123")
server.send_message("Hello", "john@gmail.com", "crabbys@gmail.com");

以下是我得到的确切错误消息：

Answer 1

你可以试试smtplib.SMTP_SSL('smtp.gmail.com',465)

SMTPServer断开连接：连接意外关闭
