.net2.0发送邮件有关问题

.net2.0发送邮件问题
配置文件里我这么写的
<system.net>
<mailSettings>
<smtp from= "tss19841011@sina.com ">
<network port= "25 " userName= "我的邮箱用户名 " password= "我的邮箱密码 " defaultCredentials= "true " host= "smtp.sina.com "/>
</smtp>
</mailSettings>
</system.net>

这是事件代码
MailMessage m_message = new MailMessage();

m_message.From = new MailAddress( "tss19841011@sina.com ");

m_message.To.Add(new MailAddress( "tss19841011@sina.com "));

m_message.Subject = "test ";

m_message.Body = "hello ";

SmtpClient m_smtpClient = new SmtpClient();

m_smtpClient.Send(m_message);
试了很多方法都报错...求高手解决或者提供点别的出路实在感激不尽 100分送上

[解决办法]
public Boolean sendemail()
{
_fromadr = "tss19841011@163.com ";
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage(_fromadr,_sendadr,_title,_content);
message.IsBodyHtml = true;
message.BodyEncoding = System.Text.Encoding.Default;
if (_bcadr != null)
{
message.CC.Add(_bcadr);
}
if (_filename != null)
{
System.Net.Mail.Attachment data = new System.Net.Mail.Attachment(_filename, System.Net.Mime.MediaTypeNames.Application.Octet);
System.Net.Mime.ContentDisposition disposition = data.ContentDisposition;
disposition.CreationDate = System.IO.File.GetCreationTime(_filename);
disposition.ModificationDate = System.IO.File.GetLastWriteTime(_filename);
disposition.ReadDate = System.IO.File.GetLastAccessTime(_filename);
message.Attachments.Add(data);
}
System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient( "smtp.163.com ");
client.Credentials = new NetworkCredential( "tss19841011 ", "*password* ");//这个要你的163的用户名和密码
try
{
client.Send(message);
return true;
}
catch (Exception ex)
{
_errormsg = ex.Message;
return false;
}

}

补充说一下，我式过sina的服务器不行，163.com的可以发～
