先上脚本，再来解释，就是这么简单直接又暴力：

# coding:utf8
import urllib2
import time
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.encode("utf-8") if isinstance(addr, unicode) else addr))

from_addr = "XXXX"  # 发件人邮件地址
to_addr = "xxxx"  # 发送给多个用户，使用逗号分隔
password = "XXX"  # 发件人邮箱的密码
smtp_server = "XXX" #发件人邮箱所有SMTP服务器地址

def format_msg(s):
    # type: (object) -> object
    msg = MIMEText(s, _subtype='html', _charset='utf-8')
    msg['From'] = _format_addr(from_addr)
    msg['To'] = _format_addr(to_addr)
    msg['Subject'] = Header(u'来自xxx的监控小黑屋', 'utf-8').encode()
    return msg.as_string()

def send_email(s):
    server = smtplib.SMTP(smtp_server, 25)
    server.set_debuglevel(0)
    server.login(from_addr, password)
    server.sendmail(from_addr, to_addr, s)
    server.quit()

list_of_sites = []   # 需要被监控的网站列表
result_of_access = '''
