mail failed

[Zeeway]

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("wu******@hotmail.com");
mailObj.From = new MailAddress(cr********@21cn.com);

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("cr********@21cn.com" ,
this.tb_mailUserPassword.Text);
client.DeliveryMethod = SmtpDeliveryMethod.Network;

client.Send(mailObj);

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

cr********@21cn.com is a correct account of mail.21cn.com,Could anyone
help 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...

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.

Perhaps my newsreader is just playing tricks on me. On my screen, the
following lines contain non-ASCII characters:
mailObj.Subject = "Óʼþ²âÊÔ";
mailObj.Body = "ºÍѶÓʼþ½ÓÊÕ²âÊԳɹ¦! ";

So, setting the coding to ASCII doesn't help. To be honest, I made a
mistake when I said that it was not UTF-8. It does appear to be UTF-8. It
does not appear to be HTML, though.

Thank you for your kind advice. I have found the reason. In fact ,my codes
work well over some SMTP Server,but not over others. This is just because
some SMTP Server needs more authorization than common ones.Thank you anyway.

Sorry I couldn't be more help. I assume you have discovered how to send
authentication information to the SMTP server, since you did not ask for
further information.

Good Luck,
