  1. Hello. My code is:

    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(""));
                    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. We are making the best efforts in order to reply to your query with in one business day<br><br>It depends on the content of your message we will contact you asap.<br><br><hr>Best Regards,<br>Onset Systems Engineering LTD";
                    //Create an object of SmtpClient by passing ur SMTP Server name and SMTP port to be used. By default port 25 can be used.
                    SmtpClient objSMTP = new SmtpClient(OnsetConfig.MailServer);
                    objSMTP.Credentials = new NetworkCredential(OnsetConfig.MailUsername, OnsetConfig.MailPassword);
                    objSMTP.UseDefaultCredentials = false;
                    //Call the Send  method of SmtpClient object and pass the MailMessage object, while will finally send the email message to the recipient's emailID
