Python基础-SMTP发送邮件

环境准备

本人注册了163注册了2个小号，便于邮件的相互发送和接收测试

开启 POP3/SMTP/IMAP

1. 具体在网易邮箱的设置->POP3/SMTP/IMAP
2. 复制下对于的SMTP 服务器地址，例如163是smtp.163.com，待会代码需要使用

发送邮件

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
# Python基础 SMTP发送邮件

from email import encoders
from email.header import Header
from email.mime.text import MIMEText
from email.utils import parseaddr, formataddr

import smtplib

def _format_addr(s):
    name, addr = parseaddr(s)
    return formataddr((Header(name, 'utf-8').encode(), addr))

# 输入寄件人邮件地址和口令
from_addr = "寄件人@163.com"
password = "寄件人的密码"

# 输入收件人地址
to_addr = "收件人@163.com"

# plain 表示纯文本
msg = MIMEText("hello, 法迪大人，我在学习Python...", "plain", "utf-8")
# 填写完整点，不然会被判断为垃圾邮件
msg['From'] = _format_addr('法迪的测试小号 <%s>' % from_addr)
msg['To'] = _format_addr('苏法迪大人 <%s>' % to_addr)
msg['Subject'] = Header('来自SMTP的问候……', 'utf-8').encode()

# 输入SMTP 服务器地址
smtp_server = 'smtp.163.com'

import smtplib

# SMTP协议默认端口是25
server = smtplib.SMTP(smtp_server, 25)
# 打印出和SMTP服务器交互的所有信息
server.set_debuglevel(1)
# 输入登陆信息
server.login(from_addr, password)
# 发送邮件
server.sendmail(from_addr, [to_addr], msg.as_string())
server.quit()
