When you are using the local IIS SMTP service, set the DeliveryMethod to PickupDirectoryFromIis. For example:

  smtpClient.DeliveryMethod = SmtpDeliveryMethod.PickupDirectoryFromIis;

This totally bypasses the network layer, and writes the messages directly to disk. Its much faster than going through the chatty SMTP protocol.

When you using the above code, it means you can get rid of this part of your code:

smtpClient.UseDefaultCredentials = false;
smtpClient.Host = "smtp.gmail.com";
smtpClient.Port = 587;
smtpClient.Credentials = new NetworkCredential(uname,pwd);
smtpClient.EnableSsl = true;
