smtp发送QQ邮件老是说我地址不匹配

[qq_30519181]

MailMessage message = new MailMessage(new MailAddress("[e-mail]"), new MailAddress("[e-mail]"));

message.Subject = "测试";
message.Body = "这是测试文件";
message.BodyEncoding = System.Text.Encoding.UTF8;
message.IsBodyHtml = false;
SmtpClient mailClient = new SmtpClient("smtp.qq.com");
mailClient.EnableSsl = true;
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = new NetworkCredential("[e-mail]", "*****");
mailClient.Send(message);



这个就是代码
但是老是报出这个错误：
服务器响应为: mail from address must be same as authorization user
我QQ邮箱的SMTP设置了，独立密码也弄了就是不知道错误出在哪里，求大神帮主，我快看花了。。。。

[编程有钱人了]

服务器响应为: mail from address must be same as authorization user 这个错误很明显 提示你，发送邮件的账号密码不正确或者不存在，没有授权
