Python自动群发邮件

import smtplib
from email import (header)
from email.mime import (text, application, multipart)
import time

def sender_mail():
    smt_p = smtplib.SMTP()
    smt_p.connect(host='smtp.qq.com', port=25)
    sender, password = '113097485@qq.com', "**************"
    smt_p.login(sender, password)
    receiver_addresses, count_num = [
        'guozhennianhua@163.com', 'xiaoxiazi99@163.com'], 1
    for email_address in receiver_addresses:
        try:
            msg = multipart.MIMEMultipart()
            msg['From'] = "zhenguo"
            msg['To'] = email_address
            msg['subject'] = header.Header('这是邮件主题通知', 'utf-8')
            msg.attach(text.MIMEText(
                '这是一封测试邮件，请勿回复本邮件~', 'plain', 'utf-8'))
            smt_p.sendmail(sender, email_address, msg.as_string())
            time.sleep(10)
            print('第%d次发送给%s' % (count_num, email_address))
            count_num = count_num + 1
        except Exception as e:
            print('第%d次给%s发送邮件异常' % (count_num, email_address))
            continue
    smt_p.quit()

sender_mail()


注意： 发送邮箱是qq邮箱，所以要在qq邮箱中设置开启SMTP服务，设置完成时会生成一个授权码，将这个授权码赋值给文中的password变量。
