            smtp.Host = ConfigurationManager.AppSettings["SMTP"];
            smtp.Credentials = new System.Net.NetworkCredential(ConfigurationManager.AppSettings["FROMEMAIL"], ConfigurationManager.AppSettings["FROMPWD"]);
            smtp.EnableSsl = true;
            smtp.Send(mail);

hey there
i solve this problem by specifying DeliveryMethod of PickupDirectoryFromIis

#  System.Net.Mail.SmtpClient myMailClient = new System.Net.Mail.SmtpClient(AppSettings("SMTPHost"));
  
    myMailClient.DeliveryMethod =  SmtpDeliveryMethod.PickupDirectoryFromIis;
     myMailClient.Send(From,To, Subject,Body);

no it still wont work mine code is

protected void Button1_Click(object sender, EventArgs e)
{
try
        {
            MailMessage mail = new MailMessage();
            mail.To.Add("[e-mail]");
            mail.From = new MailAddress("[e-mail]");
            mail.Subject = "Test E-mail";
            mail.Body = Comments.Text.ToString();
            SmtpClient smtp = new SmtpClient();
            smtp.Host = ConfigurationManager.AppSettings["SMTP"];
           
            smtp.Credentials = new System.Net.NetworkCredential(ConfigurationManager.AppSettings["FROMEMAIL"], ConfigurationManager.AppSettings["FROMPWD"]);
            smtp.EnableSsl = true;
            smtp.Send(mail);
        }
        catch (Exception exc)
        {
            Response.Write("send failure" + exc.ToString());
        }
}

[Seoconsultant78]

I think there is issue with your SMTP because i am doing mail from it its going fine and good.

Use port 587 for gmail SMTP

I am using it and works like a charm.

use the following settings in your web.config

<system.net>
    <mailSettings>
      <smtp from="[e-mail]">
        <network host="smtp.gmail.com" password="yourpassword" userName="[e-mail]" port="587"/>
      </smtp>
    </mailSettings>
  </system.net>
