注：个人邮箱发送时需要将邮箱密码设置为邮件授权码

邮件发送帮助类一：

邮件发送帮助类二（感觉这个发的快一点）：

        private int mSenderPort = 25;   //发送邮件所用的端口号（htmp协议默认为25）
        private string mSenderServerHost = "smtp.exmail.qq.com";    //发件箱的邮件服务器地址（IP形式或字符串形式均可）
        private string mSenderPassword = "密码";    //发件箱的密码
        private string mSenderUsername = "发件箱的用户名";   //发件箱的用户名
