Re: mail failed

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.

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?

perhaps it is because you told hotmail that the mail message was an HTML
message in UTF-8 yet your message body is clearly not HTML or UTF-8.

That would explain what it failed to decode the message...

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("wuhuanfa@xxxxxxxxxxx");
mailObj.From = new MailAddress(crespo1973@xxxxxxxx);

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("crespo1973@xxxxxxxx",
this.tb_mailUserPassword.Text);
client.DeliveryMethod = SmtpDeliveryMethod.Network;

client.Send(mailObj);

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