Question

I try to send email from my application. Everything seems ok, mailmessage, credentials etc.

When I debug the code it doesnt fall in to catch exception and doesnt send email. Also there is no mail queue at the server.There is no error message.

msgObj.Subject = this.Subject;        
    msgObj.From = new MailAddress(this.From , this.Display_Name);//
    msgObj.Body = this.Message;
    msgObj.IsBodyHtml = true;

    SmtpClient client = new SmtpClient(this.SMTP_Server,25);
                client.Credentials = new System.Net.NetworkCredential(SMTP_User + "@doping.com.tr", SMTP_Password);


                try
                {
                    client.Send(msgObj);
                    return true;
                }
                catch (Exception ex)
                {
                    ex.ToString();
                    return false;
                } 

What could be the problem?

Thanks.

The default settings of an SmtpClient can be configured using the System.Net configuration namespace, e.g:

<configuration>
  <system.net>
    <mailSettings>
      <smtp deliveryMethod="network" from="[e-mail]">
        <network host="localhost" port="25" defaultCredentials="true" />
      </smtp>
    </mailSettings>
  </system.net>
</configuration>

See the <smtp> Element (Network Settings) topic for more information.
