hi,my name is Marco i would like to know why the php that i am using in my page is not working ok in Peru it works but some people in usa cannot send an email please let me explain:

it works with flash the code in flash is:



enviar = function () {
if (email_txt.text.length && nombre_txt.length && mensaje_txt.length) {
if (email_txt.text.indexOf("@") != -1 && email_txt.text.indexOf(".") != -1) {
form_lv = new LoadVars();
form_lv.company = company_txt.text;
form_lv.nombre = nombre_txt.text;
form_lv.mail = email_txt.text;
form_lv.telefono = telefono_txt.text;
form_lv.urlw = urlw_txt.text;
form_lv.mensaje = mensaje_txt.text;
form_lv.sendAndLoad("http://www.ips-webdesign.com/send.php", form_lv, "POST");
mensaje_txt.text = "Sending message..";
nombre_txt.text = "";
email_txt.text = "";
telefono_txt.text = "";
urlw_txt.text = "";
company_txt.text = "";
form_lv.onLoad = function() {
if (this.estatus == "ok") {
mensaje_txt.text = "your message has been sent...";
nombre_txt.text = "";
email_txt.text = "";
telefono_txt.text = "";
urlw_txt.text = "";
company_txt.text = "";
} else {
mensaje_txt.text = "there are problems with the server,please try again";
}
};
} else {
email_txt.text = "Invalid e-mail";
}
} else {
email_txt.text = "Enter your e-mail";
nombre_txt.text = "Enter your name";

$fecha = date("D-M-y H:i");
$_POST = ($_POST ? $_POST : $HTTP_POST_VARS);
