python 发送邮件

原文：http://blog.youkuaiyun.com/marksinoberg/article/details/51506308

要发送邮件前需要做准备工作

1.启动邮箱的smtp/pop协议；开启时系统会提示给我们一个邮箱客户端的授权码，作用就是我们登陆的时候替代原来的登陆密码

如果没有启动smtp/pop协议则会提示：smtplib.SMTPAuthenticationError: (535 Error：authentication failed）

如果不是使用的授权码登录则会提示：smtplib.SMTPAuthenticationError: (550, b'User has no permission')

dome：

# -*- coding: utf-8 -*-
import smtplib
from email.mime.text import MIMEText
from email.header import Header

def email_file():
    # 获取邮箱服务器
    mail_host = 'smtp.qq.com'
    # 获取邮箱的登录邮箱
    mail_user = "xxxxxxxx@qq.com"
    # 邮箱授权码
    mail_pass = "xxxxxxx"
    # 接收邮箱，可设置为你的QQ邮箱或者其他邮箱格式为'xx.@qq.com,xx.@qq.com'
    receivers = 'xxxxxx@qq.com'
    # 构造多个部分
    message = MIMEMultipart()
    # 发件人（与登录邮箱一致）

    # 邮件主题
    message['Subject'] = Header('python测试邮件', 'utf-8')

    # 发送HTML格式的邮件
    # mail_msg = """

    message.attach(puretext)
    # ------------------------附件-------------------------------------
