Question

当我尝试从Python发送电子邮件时，收到错误消息。顺便说一句，我在Gmail帐户上进行了不太安全的配置和IMAP启用。这是下面的代码：

import smtplib

sender_email="example@gmail.com"
receveir_email="example2@gmail.com"
password=input("please enter your password")
message="this email  from python "

server=smtplib.SMTP_SSL('smptp.gmail.com',587)

server.ehlo
server.starttls()
server.login(sender_email,password)
print("login success")
server.sendmail(sender_email,receveir_email,message)
print("email has been sent to",receveir_email)
server.close()

我的错误消息：

Traceback (most recent call last):

    server=smtplib.SMTP_SSL('smptp.gmail.com',465)

我这样固定
server = smtplib.SMTP_SSL（'smtp.gmail.com'，587），但我仍然收到如下错误消息

Traceback (most recent call last):
  File "C:/Users/Administrator/PycharmProjects/codebook/Training0718.py", line 23, in <module>
    server=smtplib.SMTP_SSL('smtp.gmail.com',587)

    SMTP.__init__(self, host, port, local_hostname, timeout,

    (code, msg) = self.connect(host, port)
  File "C:\Program Files\Python38\lib\smtplib.py", line 339, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Program Files\Python38\lib\smtplib.py", line 1042, in _get_socket
    new_socket = self.context.wrap_socket(new_socket,

    self._sslobj.do_handshake()

Answer 2

我能够通过以下方式使其工作，请注意，只有在您创建并使用了应用密码后，该操作才能成功

import smtplib


password = input('please enter your password')

to = 'example2@gmail.com'
_from = 'example@gmail.com'
message = 'hello'

try:
    server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
    server.ehlo()
    server.login(_from, password)
    server.sendmail(_from, to, message)
    server.close()

except Exception as err:
    print(err)

Answer 3

首先，Gmail SMTP地址为“ smtp.gmail.com” ，而不是“ smptp.gmail.com” 。

第二，您必须选择使用SSL还是TLS，但不能两者都选择。如果选择SSL，则应使用端口465并删除：

server.starttls()

如果选择TLS，请替换：

server=smtplib.SMTP_SSL('smptp.gmail.com',587)

通过：

server=smtplib.SMTP('smptp.gmail.com',587)
