C# Customising MailAddress.From field not working

Question

I am trying to send Emails from my custom address to users using C# and googles smtp service. My problem is that when the when the user receives the message it is displayed admin@customDomain.co.uk <myAddress@gmail.com> in the from section of the email.

My problem is that I want the user to see admin@customDomain.co.uk <admin@customDomain.co.uk>. Is this possible using the google service? Or should I look at some other option? If so what?

I have tried the answers on this thread but non worked and I also found this google blog post but I cant work out how it can solve my issue

My Code

    string SmtpAddress = "smtp.gmail.com";
    int MyPort = 587;
    bool enableSSL = true;
    string MyPassword = "somePassword";
    string MyUsername = "aUsername";

    public string EmailFrom = "admin@customDomain.co.uk";
    public string Subject = "Test Subject";

public void Send(string body, BL.Customer customer)
    {
        using (MailMessage message = new MailMessage())
        {
            message.To.Add(new MailAddress(customer.EmailAddress));
            if (!String.IsNullOrEmpty(customer.SCEmailAddress))
            {
                //message.To.Add(new MailAddress(customer.SCEmailAddress));
            }
            message.From = new MailAddress(EmailFrom, EmailFrom);
            message.Subject = Subject;
            message.Body = string.Format(body);
            message.IsBodyHtml = true;

            using (var smtp = new SmtpClient())
            {
                var credential = new NetworkCredential
                {
                    UserName = MyUsername,
                    Password = MyPassword
                };
                smtp.Credentials = credential;
                smtp.Host = SmtpAddress;
                smtp.Port = MyPort;
                smtp.EnableSsl = enableSSL;
                try
                {
                    smtp.Send(message);
                }
                catch (SmtpException se)
                {
                    throw se;
                }
            }
        }
    }
