This code is working in my local but it's not working in hosting server.

Do you perhaps have to whitelist the server you are sending from?

Did they say anything less cryptic? They should be able to see whether it is the authentication or certificate or whatever.

Support team said, code is in error

hmm.. you'd expect that if the code was the problem, it wouldnt work on your local system. Have you tried using your provider's smtp relay server? --just to validate that your code is good and you are able to send mail via their system instead of one outside of their control?

Hi,
When I run the code,it shows error in Remote certificate validation.So, I added bypass certificate code lines in my coding then it runs good.

But Initially it was not running in server.

I still prefer using Gmail or Hotmail accounts for sending mail from ASP.NET. They are most trusted...

try
{
const string sender = "mtyide@gmail.com";
var from = new System.Net.Mail.MailAddress(sender, "Yandisa Mtyide");
var to = new System.Net.Mail.MailAddress(email, email);
var bcc = new System.Net.Mail.MailAddress("postmaster@paaanda.com", "postmaster@paaanda.com");

var client = new System.Net.Mail.SmtpClient
{
Host = "smtp.gmail.com",
Port = 587,
EnableSsl = true,
DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network,
UseDefaultCredentials = false,
Timeout = 30 * 1000,
Credentials = new System.Net.NetworkCredential(@from.Address, "**************")
};

using (var message = new System.Net.Mail.MailMessage())
        {
            message.From = @from;
            message.To.Add(@to);
            message.Bcc.Add(@bcc);

            message.Subject = someSubject;
            message.Body = someMessage;
            client.Send(message);
        }
