Problema mail()

[bruno-]

Non funziona.

Codice tagliuzzato qua e là:

<? if (!isset($_POST["submit"])) { ?>

[!form]

<?php
} else { 


  if (isset($_POST["fullname"]) and isset($_POST["email"]) and isset($_POST["subject"]) and isset($_POST["message"])){
  
  
  
    $name = $_POST["fullname"]; 
    $from = $_POST["email"];
    $message = $_POST["message"];
    $oggetto = $_POST["subject"];






$message = wordwrap($message, 70);

mail("[!mia mail]",$oggetto,$message,$from,"Da: $name\n",  "From: ".$from."\r\n" .
     "Reply-To: ".$from."\r\n" .
     "X-Mailer: PHP/" . phpversion());
    echo "Inviato! Grazie.";
  }
} 

?>
