Multiple headers are being sent when sending email via C# and IIS smtp

I am sending emails via my C# application the way below

MailMessage mail = new MailMessage();
mail.To.Add(srEmail);
mail.From = new MailAddress("noreply@monstermmorpg.com", srSender);
mail.Subject = srEmailTitle;
mail.Body = srEmailBody;
mail.IsBodyHtml = true;
mail.SubjectEncoding = System.Text.Encoding.UTF8;
mail.BodyEncoding = System.Text.Encoding.UTF8;
SmtpClient smtp = new SmtpClient();
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = true;
smtp.Host = "127.0.0.1";
smtp.Port = 25;
smtp.Send(mail);

I am using windows server 2008 R2 and IIS 7.5 but for mail service using IIS 6.0

Now the IIS config is the way below

enter image description here

I am not sure whether this problem caused by IIS or C# application so best to ask it. Thanks for the replays. The problem can be seen at the below i mean multiple received from headers

If you look carefully you will see there are 2 received from headers. I want to make it only single one. So basically removing the second received from header.

Well, do not use the local SMTP server. Every SMTPP server is supposed to add itself to the list for tracking. I do not really understand at all why the heck you bother - this is standard behavior.
