php mail problem

[JWG]

I have a mail problem with my server. I am sending mail with my database and using this script.

$headers .= "Return-Path: info@ofertazos.net\n";
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
$headers .= 'From: info@ofertazos.net' . "\r\n" .
'Reply-To: info@ofertazos.net' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($destinatario,$asunto,$cuerpo,$headers);
$fbO0O02 = mysql_fetch_row($rbO0O02);
echo '- '.$destinatario.'<br>';
}
echo "<b>Total mensajes: $k</b>";
cierraenlace($mc);
?>

However my server is sending as nobody@servername.com
I want to prevent sending as nobody, what do I do wrong ??
