Default mail send error :page cannot be displayed

hi ,

I am using this code for sending mail using localhost( and port 25.

 MailMessage Mail = new MailMessage();
        MailAddress ma = new MailAddress(txtFrom.Text, txtName.Text);
        Mail.From = ma;
        Mail.Subject = txtSubject.Text;
        Mail.Body = txtComment.Text;
            SmtpClient smtpMailObj = new SmtpClient();
            //eg:localhost, 192.168.0.x, replace with your server name
            smtpMailObj.Host = ConfigurationManager.AppSettings["SMTPServer"];
            //Response.Write("Your Message has been sent successfully");
        catch (Exception ex)
            //Response.Write("Message Delivery Fails");


But I get error "page cannot be displayed " when smtpMailObj.Send(Mail) executes. I have gone through almost all forums but couldnt find solution.

Help me on this topic please.

Take a look at this:

catch (Exception ex)
//Response.Write("Message Delivery Fails");

What do you think this does?

It swallows any exception that your code might throw which means you can't tell for sure what went wrong. Either write out ex.Message to the browser, or temporarily remove the try/catch block so you can see the real exception.

Using code block like this is the best way to keep yourself in the dark, clueless of the root cause of the problem...

After you find out the error, reintroduce the catch block, but don't catch a generic Exception, but one or more of the specific exceptions that the Send method might throw....
