苹果自带邮箱客户端QQ企业邮箱无法验证用户名和密码怎么办
按时间排序
不一定要用自带的啊，可以自己下一个啊
网页版本！
没用过这个客户端。没有这块资料，具体不知道怎么搞。1.建议换其他客户端。网易闪电邮。2.是不是pop
地址有错误了。3.找做好的 设置图看。祝你好远。
有独立密码直接输入独立密码。是不是设置了独立密码？不行的话只能下载QQ邮箱。再来发邮件IOS7也有遇到这个BUG。
可以常识用一下其他的客户端软件，outlook，foxmail或者闪电邮软件，闪电邮软件是网易自主研发的，要更好一些

Android QQ登录验证的小例子
1、登录时检查网络状态
2、登录加载进度条
3、登录服务器端进行验证，如果用户名和密码存在且正确，则登录，否则失败
4、注册时将用户信息保存到服务器端数据库中(MySQL)
5、记住密码功能（还不完善，只是测试）
6、对密码信息进行md5()单向加密
服务器端：
1、接收客户端发来的登录请求，如果用户名和密码存在于MySQL数据库中则返回客户端一个响应信息"success"
2、接收客户端发来的注册请求，将用户名和密码存放到MySQL数据库中
不过目前还存在很多问题，以后有时间继续更新
下面是效果图：

客户端代码：
登录代码：这里是使用HttpClient来进行与服务器端的交互的，密码加密部分只是简单的用了下md5()，如果正式的项目中可以选用非对称加密算法会更加安全
