Hello. My code is: Code: MailMessage message = new MailMessage(); MailMessage messageToUser = new MailMessage(); //Assign the MessageFromEmailID i.e. sender's EmailID message.From = new MailAddress(tbEmail.Text); messageToUser.From = new MailAddress(tbEmail.Text); //Add the MessageToEmailID i.e. recipient's EmailID message.To.Add(new MailAddress("[email protected]")); messageToUser.To.Add(new MailAddress(tbEmail.Text)); //Assign the subject of the email message.Subject = "Onset LTD | Feedback"; messageToUser.Subject = "Confirmation Letter"; message.IsBodyHtml = true; messageToUser.IsBodyHtml = true; //Assign the body of the email i.e. the message to be sent message.Body = "Hello! This is the smtp-daemon who has delivered new feedback message.<br><hr><br><b>Name:</b><br>" + tbName.Text + "<br><b>Company:</b><br>" + tbCompany.Text + "<br><b>Email</b><br>" + tbEmail.Text + "<br><b>Phone#:</b><br>" + tbPhone.Text + "<br><b>Address:</b><br>" + tbAddressLine1.Text + " " + tbAddressLine2.Text + "<br><b>Country:</b><br>" + Country.Text + "<br><b>State:</b><br>" + State.Text + "<br><b>Message:</b><br>" + tbMessage.Text + "<br><br><hr>To answer to this message you can just use reply function in your mail agent software."; messageToUser.Body = "Hello Dear " + tbName.Text + "<br><br>This is an automatic e-mail confirming your request has reached our system.

The most likely cause to this is because you are not passing SMTP authentication on your application. Our SMTP will need you to log on before it delivers the email.
