mail failed

[Crespo]

hi,everybody
I use dotnet 2005 and c sharp to deliever a mail to a certain mail
address,but it failed with messages such as "invalid parameter,the server
response: decode failed". My codes is listed belowed:
try
{
MailMessage mailObj = new MailMessage();
mailObj.To.Add("(e-mail address removed)");
mailObj.From = new MailAddress([email protected]);

mailObj.Subject = "Óʼþ²âÊÔ";
mailObj.Body = "ºÍѶÓʼþ½ÓÊÕ²âÊԳɹ¦! ";

mailObj.IsBodyHtml = true;
mailObj.Priority = MailPriority.High;
mailObj.BodyEncoding = System.Text.Encoding.UTF8;

System.Net.Mail.SmtpClient client = new
System.Net.Mail.SmtpClient("smtp.21cn.com");
client.UseDefaultCredentials = false;

client.Credentials = new
System.Net.NetworkCredential("(e-mail address removed)",
this.tb_mailUserPassword.Text);
client.DeliveryMethod = SmtpDeliveryMethod.Network;

client.Send(mailObj);

}
catch(Exception ex)
{
MessageBox.Show(ex.Message.ToString());
return;
}

(e-mail address removed) is a correct account of mail.21cn.com,Could anyone
help me?

Thanks for your answer. But following your advice,I set the
mailObj.IsBodyHtml as false and mailObj.BodyEncoding as
System.Text.Encoding.ASCII,it still failed with the same error message,Could
you further explain for me?

Thanks for your attention. In fact,my first code works well when I specify
some certain smtp servers,but doesn't work well over others which are even
correct smtp servers. Thank you very much anyway.
