Python实现发送邮件代码

代码如下：

#使用的邮箱的smtp服务器地址，这里是163的smtp地址

# 用户名
mail_user="******"
#密码
mail_pass="*****"
#邮箱的后缀，网易就是163.com
mail_postfix="163.com"

    msg['From'] = me
    msg['To'] = ";".join(to_list)                       #将收件人列表以‘；’分隔
    try:

        server.connect(mail_host)
        # 登录操作
        server.login(mail_user,mail_pass)
        server.sendmail(me, to_list, msg.as_string())
        server.close()
        return True
    except Exception, e:
        return False
if __name__ == '__main__':
    for i in range(100):                             #发送1封，上面的列表是几个人，这个就填几
        if send_mail(['******@qq.com'],"删除","请按删除键"):  #邮件主题和邮件内容
            #这是最好写点中文，如果随便写，可能会被网易当做垃圾邮件退信
            print "done!"
        else:
