I'm trying to send out an email after a button click event. When testing from my local machine everything runs smooth, the email get send out and I get the popup message notifying me that the "call has been resolved". But running from server side the page "hangs" - the screen is dimmed out which should happen until the email is sent off, but it stays like that. the email does not get sent out from server side....

C#

  MailMessage Mail = new MailMessage();
        Mail.Subject = "Call Resolved";
        Mail.To.Add(useremail);
        //  Mail.To.Add(useremail);
        Mail.From = new MailAddress("notifications@oep.co.za");

        string path = PopulateEmailImage();

        LinkedResource logo = new LinkedResource(path);
        logo.ContentId = "header";

        AlternateView av1 = AlternateView.CreateAlternateViewFromString("<html><head>" +
                            @"<meta content=""text/html; charset=utf-8"" http-equiv=""Content-Type""/> " +

        av1.LinkedResources.Add(logo);
        Mail.AlternateViews.Add(av1);

        System.Configuration.Configuration configurationFile = WebConfigurationManager.OpenWebConfiguration("~/web.config");
        MailSettingsSectionGroup mailSettings = configurationFile.GetSectionGroup("system.net/mailSettings") as MailSettingsSectionGroup;
        if (mailSettings != null)
        {
            int port = mailSettings.Smtp.Network.Port;
            string host = mailSettings.Smtp.Network.Host;
            string password = mailSettings.Smtp.Network.Password;
            string username = mailSettings.Smtp.Network.UserName;
        }
        SmtpClient SMTP = new SmtpClient();
        SMTP.Send(Mail);

<mailSettings>
  <smtp deliveryMethod="Network" from="Notifications@office.co.za">
    <network host="ipAddress" userName="notifications@oep.co.za" password="password" port="25" />
  </smtp>
</mailSettings>

The EnalbleSSl has been set to false and true - neither works. I have used telnet to check if I can connect to the ip and port - both is fine... Any help will be greatly appreciated! There are no firewalls that is blocking the email from sending out either.

Not receiving any errors through the try catch or debug... On local it works fine though....
