asp.net 发个邮件咋这么难呢

[ganzhongliang]

private void  SendMyMail()
    {
        string strHost = string.Empty;
        string strAccount = string.Empty;
        string strPwd = string.Empty;
        string strFrom = string.Empty;

        strHost = "smtp.sina.com.cn";   //STMP服务器地址
        strAccount = "ceshi1852123";       //SMTP服务帐号（我在新浪上注册的免费邮箱帐号）
        strPwd = "951230";       //SMTP服务密码
        strFrom = "[e-mail]"; //发送方邮件地址
        string to = "[e-mail]";
        string title = "这是一个测试邮件";
        string content = "测试邮件的正文";

        SmtpClient _smtpClient = new SmtpClient();
        _smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;//指定电子邮件发送方式
        _smtpClient.Host = strHost; ;//指定SMTP服务器
        _smtpClient.Credentials = new System.Net.NetworkCredential(strAccount, strPwd);//用户名和密码

        MailMessage _mailMessage = new MailMessage(strFrom, to);
        _mailMessage.Subject = title;//主题
        _mailMessage.Body = content;//内容
        _mailMessage.BodyEncoding = System.Text.Encoding.UTF8;//正文编码
        _mailMessage.IsBodyHtml = true;//设置为HTML格式
        _mailMessage.Priority = MailPriority.High;//优先级

        try
        {
            _smtpClient.Send(_mailMessage);
           // return true;
        }
        catch(Exception ex)
        {
            Response.Write(ex.Message);
           // return false;
        }


    }

用这段代码发邮件 总是抱怨：

SMTP 服务器要求安全连接或客户端未通过身份验证。 服务器响应为: Authentication required

帐号我已经指定了啊，为什么还会出这样的问题？这个问题改怎么解决，各位老大指教一哈。。。

我用GMail 发送的.挺正常的

const string ADDRESS_FROM = " @gmail.com";
const string ADDRESS_TO = "@gmail.com";
const string USER_ID = "@gmail.com";
const string PASSWORD = "1";
const string SMTP_SERVER = "smtp.gmail.com";
const int PORT = 587;

void SendMail(string smtpServer, int port)
{
SmtpClient mailClient = new SmtpClient(smtpServer, 587);
mailClient.EnableSsl = true;
NetworkCredential crendetial = new NetworkCredential(USER_ID, PASSWORD);

mailClient.Credentials = crendetial;
MailMessage message = new MailMessage(ADDRESS_FROM, ADDRESS_TO, "哇卡卡 IP",DateTime.Now.ToString() +"最新发送: "+ textBox1.Text);
message.IsBodyHtml = true;
mailClient.Send(message);
Console.WriteLine("Mail has been sent to '{0}'", ADDRESS_TO);
}

邮件smtp服务器的问题
_smtpClient.UseDefaultCredentials = false;
加上这句话试试
