PHP mail() function return false

[antoine.harlin27]

Hello!

I'm trying to make a contact form so that user can give me feedback or questions, and the form should a mail send to me.

But no matter what I put in this mail() function, it returns false.

I already looked for a solution on this forum but I didn't manage to find something that'll do the trick...

Here is my php script :

<?php
function Rec($text) {
   $text = trim($text); // delete white spaces after & before text
   if (1 === get_magic_quotes_gpc()) {
      $stripslashes = create_function('$txt', 'return stripslashes($txt);');
   } else {
      $stripslashes = create_function('$txt', 'return $txt;');
   }
   //magic quotes ?
   $text = $stripslashes($text);
   $text = htmlspecialchars($text, ENT_QUOTES); // converts to string with " and ' as well
   $text = nl2br($text);
   return $text;
};

// my e-mail address (I want the mail to be sent in) (his is not aname...)
$destinataire = 'aname@gmail.com';
// I found this somewhere but still not working
ini_set('sendmail_from', 'contact@myx10domain.x10.mx');

// French confirmation messages (meesage send) (message not send)
$message_envoye = "Votre message nous est bien parvenu!";
$message_non_envoye = "L'envoi du mail a échoué, le serveur rencontre peut être une panne temporaire.";

$nom     = (isset($_POST['nom']))     ? Rec($_POST['nom'])     : '';
$email   = (isset($_POST['email']))   ? Rec($_POST['email'])   : '';
$sujet   = (isset($_POST['sujet']))   ? Rec($_POST['sujet'])   : '';
$message = (isset($_POST['message'])) ? Rec($_POST['message']) : '';

if (($nom != '') && ($email != '') && ($sujet != '') && ($message != '')) {
   // name, email, subject and message are not empty
   $headers = 'From: '.$nom.' <'.$email.'>' . "\r\n";

    $cible = $destinataire;

   // Special chars replacement
   $message = html_entity_decode($message);
   $message = str_replace(''',"'",$message);
   $message = str_replace('’',"'",$message);
   $message = str_replace('<br>','',$message);
   $message = str_replace('<br />','',$message);

   // Sending mail...
   if (mail($cible, $sujet, $message, $headers)) {
    echo '<p>'.$message_envoye.'</p>'."\n";
   } else {
    echo '<p>'.$message_non_envoye.'</p>'."\n";
} else {
    echo '<p>'."Le formulaire a été mal rempli!".'</p>'."\n";
}
?>

Thank you in advance for your help!
